Combined Modality Therapy
The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; x-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Tomography, X-Ray Computed
Devices or objects in various imaging techniques used to visualize or enhance visualization by simulating conditions encountered in the procedure. Phantoms are used very often in procedures employing or measuring x-irradiation or radioactive material to evaluate performance. Phantoms often have properties similar to human tissue. Water demonstrates absorbing properties similar to normal tissue, hence water-filled phantoms are used to map radiation levels. Phantoms are used also as teaching aids to simulate real conditions with x-ray or ultrasonic machines. (From Iturralde, Dictionary and Handbook of Nuclear Medicine and Clinical Imaging, 1990)
Comparison of the 5-year outcome and morbidity of three-dimensional conformal radiotherapy versus transperineal permanent iodine-125 implantation for early-stage prostatic cancer. (1/1081)PURPOSE: To compare the prostate-specific antigen (PSA) relapse-free survival outcome and incidence of late toxicity for patients with early-stage prostate cancer treated at a single institution with either three-dimensional conformal radiotherapy (3D-CRT) or transperineal permanent implantation (TPI) with iodine-125 seeds. MATERIALS AND METHODS: Patients with favorable-risk prostate cancer, defined as a pretreatment PSA of less than or equal to 10.0 ng/mL, Gleason score of 6 or lower, and stage less than or equal to T2b, were selected for this analysis. Between 1989 and 1996, 137 such patients were treated with 3D-CRT and 145 with TPI. The median ages of the 3D-CRT and TPI groups were 68 years and 64 years, respectively. The median dose of 3D-CRT was 70.2 Gy, and the median implant dose was 150 Gy. Prostate-specific antigen relapse was defined according to the American Society of Therapeutic Radiation Oncology Consensus Statement, and toxicity was graded according to the Radiation Therapy Oncology Group morbidity scoring scale. The median follow-up times for the 3D-CRT and TPI groups were 36 and 24 months, respectively. RESULTS: Eleven patients (8%) in the 3D-CRT group and 12 patients (8%) in the TPI group developed a biochemical relapse. The 5-year PSA relapse-free survival rates for the 3D-CRT and the TPI groups were 88% and 82%, respectively (P = .09). Protracted grade 2 urinary symptoms were more prevalent among patients treated with TPI compared with 3D-CRT. Grade 2 urinary toxicity, which was manifest after the implant and persisted for more than 1 year after this procedure, was observed in 45 patients (31%) in the TPI group. In these 45 patients, the median duration of grade 2 urinary symptoms was 23 months (range, 12 to 70 months). On the other hand, acute grade 2 urinary symptoms resolved within 4 to 6 weeks after completion of 3D-CRT, and the 5-year actuarial likelihood of late grade 2 urinary toxicity for the 3D-CRT group was only 8%. The 5-year actuarial likelihood of developing a urethral stricture (grade 3 urinary toxicity) for the 3D-CRT and TPI groups was 2% and 12%, respectively (P<.0002). Of 45 patients who developed grade 2 or higher urinary toxicity after TPI, the likelihood of resolution or significant improvement of these symptoms at 36 months from onset was 59%. The 5-year likelihood of grade 2 late rectal toxicity for the 3D-CRT and TPI patients was similar (6% and 11%, respectively; P = .97). No patient in either group developed grade 3 or higher late rectal toxicity. The 5-year likelihood of posttreatment erectile dysfunction among patients who were initially potent before therapy was 43% for the 3D-CRT group and 53% for the TPI group (P = .52). CONCLUSION: Both 3D-CRT and TPI are associated with an excellent PSA outcome for patients with early-stage prostate cancer. Urinary toxicities are more prevalent for the TPI group and subsequently resolve or improve in most patients. In addition to evaluating long-term follow-up, future comparisons will require detailed quality-of-life assessments to further determine the impact of these toxicities on the overall well-being and quality of life of the individual patient.

Pelvic radiation with concurrent chemotherapy compared with pelvic and para-aortic radiation for high-risk cervical cancer. (2/1081)BACKGROUND AND METHODS: We compared the effect of radiotherapy to a pelvic and para-aortic field with that of pelvic radiation and concurrent chemotherapy with fluorouracil and cisplatin in women with advanced cervical cancer. Between 1990 and 1997, 403 women with advanced cervical cancer confined to the pelvis (stages IIB through IVA or stage IB or IIa with a tumor diameter of at least 5 cm or involvement of pelvic lymph nodes) were randomly assigned to receive either 45 Gy of radiation to the pelvis and para-aortic lymph nodes or 45 Gy of radiation to the pelvis alone plus two cycles of fluorouracil and cisplatin (days 1 through 5 and days 22 through 26 of radiation). Patients were then to receive one or two applications of low-dose-rate intracavitary radiation, with a third cycle of chemotherapy planned for the second intracavitary procedure in the combined-therapy group. RESULTS: Of the 403 eligible patients, 193 in each group could be evaluated. The median duration of follow-up was 43 months. Estimated cumulative rates of survival at five years were 73 percent among patients treated with radiotherapy and chemotherapy and 58 percent among patients treated with radiotherapy alone (P=0.004). Cumulative rates of disease-free survival at five years were 67 percent among patients in the combined-therapy group and 40 percent among patients in the radiotherapy group (P<0.001). The rates of both distant metastases (P<0.001) and locoregional recurrences (P<0.001) were significantly higher among patients treated with radiotherapy alone. The seriousness of side effects was similar in the two groups, with a higher rate of reversible hematologic effects in the combined-therapy group. CONCLUSIONS: The addition of chemotherapy with fluorouracil and cisplatin to treatment with external-beam and intracavitary radiation significantly improved survival among women with locally advanced cervical cancer.

Concurrent cisplatin-based radiotherapy and chemotherapy for locally advanced cervical cancer. (3/1081)BACKGROUND AND METHODS: On behalf of the Gynecologic Oncology Group, we performed a randomized trial of radiotherapy in combination with three concurrent chemotherapy regimens -- cisplatin alone; cisplatin, fluorouracil, and hydroxyurea; and hydroxyurea alone -- in patients with locally advanced cervical cancer. Women with primary untreated invasive squamous-cell carcinoma, adenosquamous carcinoma, or adenocarcinoma of the cervix of stage IIB, III, or IVA, without involvement of the para-aortic lymph nodes, were enrolled. The patients had to have a leukocyte count of at least 3000 per cubic millimeter, a platelet count of at least 100,000 per cubic millimeter, a serum creatinine level no higher than 2 mg per deciliter (177 micromol per liter), and adequate hepatic function. All patients received external-beam radiotherapy according to a strict protocol. Patients were randomly assigned to receive one of three chemotherapy regimens: 40 mg of cisplatin per square meter of body-surface area per week for six weeks (group 1); 50 mg of cisplatin per square meter on days 1 and 29, followed by 4 g of fluorouracil per square meter given as a 96-hour infusion on days 1 and 29, and 2 g of oral hydroxyurea per square meter twice weekly for six weeks (group 2); or 3 g of oral hydroxyurea per square meter twice weekly for six weeks (group 3). RESULTS: The analysis included 526 women. The median duration of follow-up was 35 months. Both groups that received cisplatin had a higher rate of progression-free survival than the group that received hydroxyurea alone (P<0.001 for both comparisons). The relative risks of progression of disease or death were 0.57 (95 percent confidence interval, 0.42 to 0.78) in group 1 and 0.55 (95 percent confidence interval, 0.40 to 0.75) in group 2, as compared with group 3. The overall survival rate was significantly higher in groups 1 and 2 than in group 3, with relative risks of death of 0.61 (95 percent confidence interval, 0.44 to 0.85) and 0.58 (95 percent confidence interval, 0.41 to 0.81), respectively. CONCLUSIONS: Regimens of radiotherapy and chemotherapy that contain cisplatin improve the rates of survival and progression-free survival among women with locally advanced cervical cancer. (+info)
Cisplatin, radiation, and adjuvant hysterectomy compared with radiation and adjuvant hysterectomy for bulky stage IB cervical carcinoma. (4/1081)BACKGROUND: Bulky stage IB cervical cancers have a poorer prognosis than smaller stage I cervical cancers. For the Gynecologic Oncology Group, we conducted a trial to determine whether weekly infusions of cisplatin during radiotherapy improve progression-free and overall survival among patients with bulky stage IB cervical cancer. METHODS: Women with bulky stage IB cervical cancers (tumor, > or =4 cm in diameter) were randomly assigned to receive radiotherapy alone or in combination with cisplatin (40 mg per square meter of body-surface area once a week for up to six doses; maximal weekly dose, 70 mg), followed in all patients by adjuvant hysterectomy. Women with evidence of lymphadenopathy on computed tomographic scanning or lymphangiography were ineligible unless histologic analysis showed that there was no lymph-node involvement. The cumulative dose of external pelvic and intracavitary radiation was 75 Gy to point A (cervical parametrium) and 55 Gy to point B (pelvic wall). Cisplatin was given during external radiotherapy, and adjuvant hysterectomy was performed three to six weeks later. RESULTS: The relative risks of progression of disease and death among the 183 women assigned to receive radiotherapy and chemotherapy with cisplatin, as compared with the 186 women assigned to receive radiotherapy alone, were 0.51 (95 percent confidence interval, 0.34 to 0.75) and 0.54 (95 percent confidence interval, 0.34 to 0.86), respectively. The rates of both progression-free survival (P<0.001) and overall survival (P=0.008) were significantly higher in the combined-therapy group at four years. In the combined-therapy group there were higher frequencies of transient grade 3 (moderate) and grade 4 (severe) adverse hematologic effects (21 percent, vs. 2 percent in the radiotherapy group) and adverse gastrointestinal effects (14 percent vs. 5 percent). CONCLUSIONS: Adding weekly infusions of cisplatin to pelvic radiotherapy followed by hysterectomy significantly reduced the risk of disease recurrence and death in women with bulky stage IB cervical cancers.

The Denolin Lecture 1998. Towards measurement of coronary blood flow in patients and its alteration by interventions. (5/1081)AIM: Several methods of measuring coronary blood flow in intact conscious man are reviewed, on the basis of personal contributions or the experiences of our teams. METHODS AND RESULTS: It is important to distinguish between global, regional and transmural blood flow measurements. The advantages and limitations of the following methods are discussed: diffusible inert and radioactive tracers, dye dilution, roentgendensitometry, magnetic resonance imaging and contrast echocardiography. In interventional cardiology it is most important to be able to measure flow through single coronary vessels. Information on coronary artery Doppler velocity during vasodilation and at rest is less useful than the concept of fractional flow reserve. This is based on pressure measurements under maximal vasodilation to ascertain the presence of borderline flow-limiting lesions. This information is necessary in order to decide whether to proceed with angioplasty or not. CONCLUSIONS: The historical design of percutaneous coronary angioplasty and beta-irradiation of coronary restenosis, established under the author's guidance, are put into perspective. The author pays tribute to many excellent colleagues who worked with him at the Zurich and Geneva University Hospitals. (+info)
Bromodeoxyuridine alternating with radiation for advanced uterine cervix cancer: a phase I and drug incorporation study. (6/1081)PURPOSE: Preclinical studies show a significant increase in the ratio of the radiosensitizer bromodeoxyuridine (BUdR) in tumors versus the intestinal mucosa during the drug elimination period, compared with the ratio during drug infusion. We constructed a phase I study in patients with locally advanced cervix cancer, using alternating cycles of BUdR and radiation therapy (RT). PATIENTS AND METHODS: Eighteen patients with stage IIB to IVA cervix cancer participated. A treatment cycle consisted of a 4-day BUdR infusion followed by a week of pelvic RT, 15 Gy twice daily in 1.5-Gy fractions. After three cycles, additional BUdR was infused, followed by brachytherapy. The fraction of thymidine replaced by BUdR and the fraction of cells incorporating BUdR were determined in rectal mucosa and tumor biopsies at the end of the first BUdR infusion (day 5), at the middle of the first RT week (day 10), and at the time of brachytherapy. RESULTS: Dose-limiting toxicity was observed in one of 16 patients receiving 1,000 mg/m2/d x 4 days and in both patients receiving 1,333 mg/m2/d x 4 days each cycle. After a median follow-up of 39 months, 12 patients (66%) were free of pelvic disease and nine (50%) were alive and disease free. The ratio of tumor to rectum BUdR incorporation averaged 1.5 to 1.8 and did not differ significantly between day 5 and day 10. A trend toward reduced ratio was observed at brachytherapy. Drug-containing cells in rectal biopsies migrated from the crypts to the mucosal surface. CONCLUSION: In this schedule, 1,000 mg/m2/d is the maximum-tolerated dose of BUdR. BUdR incorporation levels in tumors were consistent with clinically significant radiosensitization. The migration of BUdR-containing rectal mucosa cells from the crypts to the surface at the time of RT suggests that this regimen may offer a relative sparing of the mucosa from radiosensitization.

Late coronary occlusion after intracoronary brachytherapy. (7/1081)BACKGROUND: Intracoronary brachytherapy appears to be a promising technology to prevent restenosis. Presently, limited data are available regarding the late safety of this therapeutic modality. The aim of the study was to determine the incidence of late (>1 month) thrombosis after PTCA and radiotherapy. METHODS AND RESULTS: From April 1997 to March 1999, we successfully treated 108 patients with PTCA followed by intracoronary beta-radiation. Ninety-one patients have completed at least 2 months of clinical follow-up. Of these patients, 6.6% (6 patients) presented with sudden thrombotic events confirmed by angiography 2 to 15 months after intervention (2 balloon angioplasty and 4 stent). Some factors (overlapping stents, unhealed dissection) may have triggered the thrombosis process, but the timing of the event is extremely unusual. Therefore, the effect of radiation on delaying the healing process and maintaining a thrombogenic coronary surface is proposed as the most plausible mechanism to explain such late events. CONCLUSIONS: Late and sudden thrombosis after PTCA followed by intracoronary radiotherapy is a new phenomenon in interventional cardiology. (+info)
Proliferative potential of malignant glioma cells before and after interstitial brachytherapy. (8/1081)The viability of tumor cells in radionecrotic tissue after interstitial brachytherapy (BRTX) was evaluated using immunohistochemical markers of proliferative potential in primary and recurrent tumors. Tumor specimens from 30 patients with malignant gliomas (14 anaplastic astrocytomas, 16 glioblastomas) taken before and after BRTX were examined using MIB-1 monoclonal antibody. Histological examination of specimens obtained by craniotomy or stereotactic biopsy after BRTX revealed tumor recurrence in 18 patients and radionecrosis in 12 patients including two with pure radionecrosis and 10 with a mixture of both tumor and radionecrosis. The MIB-1 index of the tumors with radionecrosis was 7.6 +/- 5.5%, and that of the primary tumors was 17.0 +/- 11.2%, showing a significant difference (p < 0.05). There was no significant difference between the MIB-1 index of the primary tumors with local recurrence after BRTX and the primary tumors which underwent radionecrosis. Although morphologically viable tumor cells were found in the radionecrotic tissue, BRTX causes a reduction in the proliferative potential of these tumor cells. (+info)

High-dose rate brachytherapy (HDR-BT) is an effective therapy modality for patients with localized prostate cancer (CaP) of all risks. In contrast to an external beam radiotherapy and low-dose rate brachytherapy (LDR-BT), in these patients, the interstitial HDR-BT, the total radiation dose and fractionation is not unambiguously defined. Between 2009-2018 35 patients with localized CaP (6 (17.1%) low-risk patients, 21 (60%) patients medium-risk and 8 (22.9%) high-risk) were treated with HDR-BT, as the only treatment (monotherapy) in the General Hospital Medical System Belgrade. The group of patients with medium-risk and high-risk were merged into a single group (group with a higher-risk). Technique implementation of HDR-BT was similar as in the LDR-BT. Application of needles, segmentation, delineation, and planning of HDR-BT was performed with transrectal ultrasound (TRUS) and izocentrically mounted radioscopic C-arm. Irradiation was done on the Microselectron-HDR brachytherapy unit wit...h a ...

Prostate Seeds - American Brachytherapy Society
A noteworthy study recently published in JAMA® (The Journal of the American Medical Association) by a multi-institutional group of prostate cancer experts, concluded that men with high risk prostate cancer treated with external beam radiation therapy (EBRT), brachytherapy seed implant, and hormone deprivation therapy, were associated with significantly better prostate cancer-specific mortality rates (deaths caused by prostate cancer) compared to radical prostatectomy or EBRT with hormone deprivation therapy.2. Additionally, researchers from the British Columbia Cancer Agency, published a landmark, Level 1 evidence trial, that concluded men with Intermediate & High-Risk prostate cancer randomized to low-dose brachytherapy boost, EBRT, and hormone deprivation (versus men randomized to EBRT boost, EBRT and hormone deprivation therapy) were twice as likely to be free of biochemical failure (detectable and rising Prostate Specific Antigen (PSA)) at a median follow-up of 6.5 years.3.

Brian Moran,M.D. - Brachytherapy - Best Radiation Treatment for Prostate Cancer | Prostate Cancer Treatment | Chicago Prostate...
There has been much controversy over the past several years regarding the best treatment option for prostate cancer. To date, there is no clear-cut data to prove the advantage of surgery over other treatment options. Recently, there has been a new enthusiasm for IMRT (Intensity Modulated Radiation Therapy) and proton beam radiation therapy for the treatment of prostate cancer. Again, there is no data to support that either therapy is superior to brachytherapy for the treatment of prostate cancer. However, there is data suggesting that brachytherapy is superior to IMRT. Data from the latest Meeting of the American Brachytherapy Society, presented by Michael Zelefsky, M.D. from Sloan-Kettering Cancer Center, NY (June 2009), compared 2292 patients that were treated with IMRT or brachytherapy. Results found that the 7-year PSA relapse-free survival (PRFS) for low-risk patients was 92.4% for patients treated with brachytherapy and 91.6% for patients treated with IMRT. However, the 7-year PRFS for ...

Because of more rapid dose delivery with HDR compared to LDR brachytherapy (15 minutes vs. 6 months) and more precise control of dose to adjacent critical structures (prostatic and bulbo-membranous urethra and anterior rectal wall), HDR prostate brachytherapy has been associated with more rapid recovery from acute symptoms and a more favorable side effect protocol when used as a boost in combination with external beam radiotherapy. The hypothesis is that this advantage will be maintained when brachytherapy is used as monotherapy without the addition of external beam radiation.. Justification:. In British Columbia, LDR prostate brachytherapy is the current standard for selected men with favorable risk prostate cancer who are not suitable for, or ...
Many Women Treated With Brachytherapy Arent Good Candidates
Even though the women in the study were treated with brachytherapy before the ASTRO guidelines were developed, the results suggest that many women unsuitable for brachytherapy are getting brachytherapy. This possibility is more of a concern because brachytherapy use has continued to increase since 2007 when the last of the patients in this study were treated.. Findings from another large study suggest that brachytherapy may not be as effective as whole-breast radiation therapy at reducing recurrence risk. Women in that study who got brachytherapy after lumpectomy for early-stage breast cancer were nearly twice as likely to later have a mastectomy because of cancer recurrence compared to women who got traditional whole-breast radiation therapy. That study also found that treatment complications -- such as rib fracture, breakdown of fat in the breast (fat necrosis), breast pain, and inflammation in the lungs -- were more likely among women treated with brachytherapy. Some of these higher ...
Calculating Curved Needles Deformation in Automated High-Dose Rate Brachytherapy Operations | Science Publications
The article outlines the approach to applying the mechatronic technologies and robotic systems in carrying out the brachytherapy operations. To calculate the elastic state of the flexible needles of different geometry in the prostate model, a mathematical model of the flexible needle deformation has been applied which took into account the medium reaction and was based on the theory of flexible and elastic rods. The numeric calculations for different types of needles have been introduced for the first time. Also for the first time the advantages of applying flexible needles for brachytherapy procedure have been mathematically justified.

Most recent papers with the keyword Endobronchial brachytherapy | Read by QxMD
The co-incidence of synchronous intraepithelial neoplasia and early stage invasive lung cancer is not a rare phenomenon. The need for curative treatment and the invasive potential of squamous cell pulmonary carcinoma in situ have been a topic of controversy. Surgical resection still remains the treatment of choice. Varieties of endoscopic techniques such as brachytherapy were developed as an alternative to surgery in selected patients. External beam radiation therapy has been used traditionally in combination with endobronchial brachytherapy in the treatment of roentgenographically occult lung cancer, and can be offered for all patients, but is handicapped, because these tumors are radiographically invisible ...

Enucleation After Iodine-125 Plaque Brachytherapy in Patients with Large Choroidal Melanomas | IOVS | ARVO Journals
Purpose: Treatment of choroidal melanoma (CMM) with either iodine-125 (I125) plaque brachytherapy or enucleation yields similar survival outcomes. As such, we have used brachytherapy as primary treatment for large CMMs for more than a decade. Herein, we evaluate our cohort of patients with large CMM initially treated with plaque brachytherapy to determine rate of and factors associated with secondary enucleation.. Methods: A retrospective chart review of patients with large CMMs diagnosed and treated at our institution from January 1, 1988 to February 1 2013. Main outcome measures were need for secondary enucleation, local tumor recurrence, all cause mortality, development of metastases, initial apical tumor height and maximal basal diameter.. Results: 245 patients with large CMM were treated primarily with plaque brachytherapy. Local control was achieved in 230 patients (93.8%). Of the 15 patients (6.2%) with local recurrence, 8 underwent secondary enucleation and 7 deferred further treatment. ...
A Device for the Automated Loading and Detection of Brachytherapy Elements Using Nonmechanical Methods for use in Prostate...
Within the recent resurgence of brachytherapy as treatment for prostate cancer, many new devices have been conceived in the preparation of surgical brachytherapy equipment. Specifically, this work encompasses the automated preparation of preloaded surgical brachytherapy applicators or needles through the loading of radioactive seed elements and benign spacer elements. While traditionally a manual operation, current device methodology in this application revolves around semi-automatic mechanical interaction within the element loading procedure. Mechanical interaction can subject elements to damage, specifically seed elements due to thin metallic construct. Damage to elements within a loading system can result in failure of the performed brachytherapy treatment causing potential harm to the patient. Hesitancy in acceptance of these mechanical separation element loading devices can be attributed to the failure nature of these devices. This work seeks to solve the current issue of element damage ...

Scott Hamilton Cares
Doctors can use brachytherapy alone or in addition to external-beam radiation therapy to provide a boost of radiation to a tumor while sparing surrounding normal tissue. Brachytherapy may be able to deliver higher doses of radiation to some cancers than external-beam radiation therapy while causing less damage to normal tissue.. Several brachytherapy techniques are used in cancer treatment, based on locations of cancer, dose and period of treatment. Interstitial brachytherapy uses a radiation source placed within tumor tissue, such as within a prostate tumor. Intracavitary brachytherapy uses a source placed within a surgical cavity or a body cavity, such as the chest cavity, near a tumor. Episcleral brachytherapy, which is used to treat melanoma inside the eye, uses a source that is attached to the eye.. In interstitial brachytherapy, radioactive isotopes are sealed in tiny pellets, the size of a grain of rice. These seeds are placed in the body using delivery devices, such as needles, ...

Salvage Brachytherapy After External-Beam Irradiation for Prostate Cancer | Cancer Network | The Oncology Journal
The options available for patients with recurrent prostate cancer are limited. Men who have failed external-beam irradiation as the primary treatment are rarely considered for potentially curative salvage therapy. Traditionally, only palliative treatments have been offered with hormonal intervention or simple observation. A significant percentage of these patients have only locally recurrent cancer and are thus candidates for curative salvage therapy. Permanent brachytherapy with iodine-125 or palladium-103 has been used in an attempt to eradicate the remaining prostate cancer and prevent the need for additional intervention. It is critical in this population to identify patients most likely to have distant metastases or who are unlikely to suffer death or morbidity from their recurrence, in order to avoid potential treatment morbidity in those unlikely to benefit from any intervention. Following salvage brachytherapy, up to 98% of these cancers may be locally controlled, and 5-year freedom from second
AAPM Reports - Dosimetry of Interstitial Brachytherapy Sources
The dosimetry of sources used in interstitial brachytherapy has been the subject of considerable research in recent years. A number of articles have appeared (Appendix C) introducing revised calibration standards, source strength specification quantities, and dose calculation formalisms. Some of these articles advocate revision of basic dosimetry data, including dose rate constants, radial dose functions, and anisotropy functions for 192Ir, 125I, and 103Pd sources. In particular, the Interstitial Collaborative Working Group (ICWG), which was sponsored by the National Cancer Institute, has completed its final report. With all these reports appearing in the literature, the medical physics community is faced with a confusing situation regarding the selection of dosimetry data. Therefore, the Radiation Therapy Committee of the American Association of Physicists in Medicine (AAPM) in 1988 formed Task Group No. 43 to review the recent publications on the dosimetry of interstitial brachytherapy sources ...

Apparatus, systems, and methods are provided for delivering brachytherapy into a target tissue region, e.g., a breast. In some embodiments, a flexible brachytherapy device is implanted that includes a therapy delivery portion having one or more radioactive sources securely retained thereto, and a tail portion extending from the therapy delivery portion. The brachytherapy device may be implanted in a helical configuration within the target tissue region. To assist in placement and removal of the brachytherapy device, a tubular sheath may be implanted by attaching (e.g., sliding over) a helically coiled needle that is advanced into the body by screw-like rotation. Once implanted, the sheath and the brachytherapy device may extend outside the body, where they may be folded and secured flat against the skin. The device and sheath may be removed at therapy completion.
The impact of inter-fraction changes for perineal template-based interstitial gynecologic brachytherapy implants
For patients with advanced or recurrent gynecologic malignancies, interstitial brachytherapy (ISBT) has been shown to improve local control, while maintaining an acceptable toxicity profile . Patients with complex and bulky disease are often indicated for the brachytherapy component to be delivered using a perineal template to guide the ISBT implant. Though treatment regimens vary, the application of the prescription dose is commonly delivered over three to six fractions from a single perineal implant that is sutured to the patient [1,2,3]. These fractions are delivered a minimum of six hours apart, with the total treatment time spanning multiple, consecutive days. To aid in the safe adoption of complex high-dose-rate (HDR) brachytherapy gynecologic treatments, consensus-based commissioning guidelines provide a standardized approach to minimize treatment errors ; however, the availability of institutional resources create differences in practical clinical implementation, which often ...
