Pelvic bone complications following radiation therapy of gynecologic malignancies: clinical evaluation of radiation-induced pelvic insufficiency fractures

OBJECTIVE: To investigate the incidence, clinical and imaging finding of insufficiency fractures (IF) of the female pelvis following radiation therapy. METHODS: We reviewed the radiation oncology records of 158 patients with gynecologic malignancies who underwent external beam radiation therapy of the whole pelvis between April 1993 and March 2004. All patients underwent computed tomography (CT) scan every 6 months in follow-up after radiation therapy and magnetic resonance imaging (MRI) and radionuclide bone scan were added when the patients complained of a pelvic pain. RESULTS: Eighteen of 158 patients (11.4%) developed IF in the irradiated field with a median interval of 6 months (range 3-51) from the completion of external beam radiation therapy. The cumulative incidence of symptomatic IF at 5 years calculated with Kaplan-Meyer methods was 13%. Median age of the patients who developed IF was 70 years (range 48-88), and all of them were postmenopausal. IF occurred in the sacloiliac joints, upper limb of pubic bone, acetabulum, sacral body and 5th lumbar vertebra. Twelve of 18 patients had multiple lesions and 8 had symmetric longitudinal fracture lines parallel to the sacroiliac joints. Avoidance of weight bearing by bed rest and analgesics provided good pain relief in all patients, although symptoms lasted from 3 to 20 months. CONCLUSIONS: Radiation-induced pelvic IF following radiation therapy for gynecologic malignancies were frequently observed in the postmenopausal patients within 1 year after external beam radiation therapy. Symmetric fractures of the both sacroiliac joints were the characteristic pattern of pelvic IF. Knowledge of characteristic imaging pattern of IF is essential in order to rule out the bone metastasis. Therapy recommendations are conservative with analgesics.     

Radiation treatment of advanced or recurrent granulosa cell tumor of the ovary

BACKGROUND: Because granulosa cell tumors of the ovary are rare, the optimal treatment for women with gross residual disease after primary surgery or recurrence is not known. Our objective was to review the results of radiotherapy for advanced or recurrent granulosa cell tumor of the ovary. METHODS: This retrospective review identified 34 patients with ovarian granulosa cell tumors treated with radiation at the University of Texas M. D. Anderson Cancer Center between 1949 and 1988. Fourteen received treatment for clinically measurable disease; 20 received adjuvant radiotherapy after surgery for minimal residual (<1 cm) or microscopic residual disease. The 14 patients with measurable disease formed the basis for this review. RESULTS: Ten of 14 patients were treated with moving-strip whole-abdomen radiation (27-28 Gy), 9 with 60Co, and 1 with 6-MeV photons and a pelvic boost of 28 Gy with 22-25 MeV photons. The other 4 patients were treated with pelvic radiotherapy (45-61 Gy) with 22-25 MeV photons. Six of 14 patients (43%) had a clinical complete response to radiotherapy, with a median follow-up of 13 years (range, 5-21 years). Three of 6 who responded to radiation had relapse 4-5 years later; 2 of these 3 died of disease and 1 was alive with disease at last follow-up. Three responders remain alive without evidence of disease 10-21 years after treatment. The 8 nonresponders had a median survival of 12.3 months (range, 1-60 months). CONCLUSIONS: Radiotherapy can induce a clinical response with occasional long-term remission in patients with persistent or recurrent granulosa cell tumor of the ovary.     

External pelvic radiation therapy in stage IC endometrial carcinoma

OBJECTIVE: To evaluate outcomes of patients with stage IC endometrial carcinoma treated with external whole pelvic radiation but not vaginal brachytherapy. METHODS: Sixty-one women with stage IC endometrial carcinoma had postoperative pelvic radiation without vaginal brachytherapy. The median age was 69 years (range 44-87 years). Most subjects had histologic findings of adenocarcinoma (71%) and grade 2 or 3 disease (74%). The median pelvic irradiation dose was 48.6 Gy (range 43.2-50.4 Gy). No patients received adjuvant chemotherapy or hormonal therapy. The median follow-up time was 69.5 months (range 7-196 months). RESULTS: The 5-year actuarial disease-free and overall survivals of the entire group were 86.7% and 97.6%, respectively. No patient developed local (vaginal) recurrence. One patient had recurrent disease in the lateral pelvis. Ten patients (16.4%) had distant (extrapelvic) metastases. No serious sequelae were noted, including vaginal necrosis, small bowel obstruction, proctitis, or fistulae. CONCLUSION: Local control was excellent in stage IC endometrial carcinoma treated with adjuvant radiation therapy alone. Attention needs to be focused on efforts to control extrapelvic recurrence in patients with this disease.     

Radiation therapy for pelvic lymph node metastasis from uterine cervical cancer

Objectives

This study aimed to evaluate the efficacy of radiation therapy for pelvic lymph node metastasis from uterine cervical cancer and identify an optimal radiation regimen.

Methods

A total of 111 metastatic pelvic lymph nodes, ranging from 11 to 56 mm (median, 25 mm) on CT/MRI, in 62 patients with uterine cervical cancer were treated initially with curative radiation therapy, with 46 patients receiving concurrent chemotherapy. Total radiation doses ranged from 45 to 61.2 Gy (median, 50.4 Gy) in 1.8–2 Gy (median, 1.8 Gy) fractions.

Results

At a median follow-up of 33 months, 46 of the 62 patients survived. Only 2 irradiated lymph nodes, 24 and 28 mm in diameter, in 1 patient progressed after irradiation alone with 50.4 Gy in 1.8 Gy fractions. All 33 metastatic lymph nodes ≥ 30 mm in diameter were controlled by irradiation at a median dose of 55.8 Gy. The 3-year lymph node-progression free rates were 98.2% in all 62 patients and 98.0% in all 111 metastatic lymph nodes. Except for transient hematologic reactions, 2 patients developed grade ≥ 3 therapy-related toxicities, 1 with an ulcer and the other with perforation of the sigmoid colon. In addition, 2 patients experienced ileus after irradiation.

Conclusions

Radiation therapy effectively controlled pelvic lymph node metastases in patients with uterine cervical cancer, with most nodes < 24 mm in diameter controlled by total doses of 50.4 Gy in 1.8 Gy fractions and larger nodes controlled by 55.8 Gy, particularly with concurrent chemotherapy. Higher doses to metastatic lymph nodes may increase intestinal toxicities.     

Extended-field radiotherapy and high-dose-rate brachytherapy with concurrent and adjuvant cisplatin-based chemotherapy for locally advanced cervical cancer: a phase I/II study

OBJECTIVE: The purpose of this prospective study was to investigate the toxicity and efficacy of integrating extended-field para-aortic and pelvic external radiation, high-dose-rate intracavity brachytherapy, and concurrent and adjuvant cisplatin-based chemotherapy for locally advanced cervical cancer. METHOD: A phase I/II study was performed from 1998 to 2003 including sixty-three patients with both clinical FIGO and MRI/CT-based TNM stage IIB-IVA cervical cancer. Patients were treated with extended-field external radiation to the para-aortic and pelvic regions with 45 Gy in 25 fractions, and an additional boost to the gross nodes to 50.4 Gy and the parametrium to 59.4 Gy. Patients also received a high-dose-rate (HDR) intracavity brachytherapy with doses of 22-31 Gy to point A in 4-6 fractions. Concurrently, two cycles of cisplatin (50-80 mg/m(2)) were administered in weeks 1 and 5 during radiotherapy, as well as two cycles of cisplatin (60-80 mg/m(2)) for 1 day and 5-fluorouracil (600-800 mg/m(2)) for 4 days at 1 and 2 months after completion of radiotherapy. The treatment-related acute and late side effects were evaluated using RTOG criteria, and the disease control and survival rate were calculated using the Kaplan-Meier method. The median follow-up interval was 36 months. RESULTS: All sixty-three patients completed the planned extended-field radiotherapy and high-dose-rate brachytherapy with 2 concurrent cycles of cisplatin. Fifty-eight (92%) patients received 2 cycles of the post-radiation adjuvant chemotherapy of cisplatin and 5-fluorouracil. RTOG grade III acute toxicity was gastrointestinal (2%) and hematological (10%). No patient had grade IV acute toxicity. Late grades III-IV morbidity actuarial risk of 6% at 6.5 years primarily involved the injuries to the bowels requiring surgical intervention for intestinal obstruction or fistula formation. Initial sites of recurrence were locoregional failure alone (pelvic and para-aortic regions within the radiation field), 3%; distant metastases only, 8%; and locoregional failure plus distant metastases, 8%. The observed rates at 3-year and 5-year of locoregional control, freedom from distant metastasis, and overall survival were 86% and 86%, 81% and 81%, and 81% and 77%, respectively. CONCLUSION: Incorporating HDR brachytherapy into a regimen including concurrent chemotherapy and extended radiation appears safe and effective.     

Clinical outcome with adjuvant treatment of endometrial carcinoma using intensity-modulated radiation therapy

OBJECTIVE: To assess local control and chronic toxicity with IMRT for adjuvant treatment of endometrial carcinoma. METHODS: Forty-seven patients with endometrial cancer were treated with adjuvant IMRT and HDR brachytherapy (HDRB). The external beam dose was between 45 and 50.4 Gy, and all patients received 10 Gy in 2 fractions of HDRB to the vaginal cuff. Eight of these patients were treated with extended field to include the paraaortic region. RESULTS: IMRT dosimetry showed excellent coverage of the planning target volume (PTV) with mean PTV 95, PTV 110 and PTV 120 of 97.8%, 8.2% and 0.9% respectively. At a median follow-up of 20 months, four patients have recurred at extra pelvic sites. No patient had pelvic recurrence. The treatment was well tolerated with late toxicities as follows: small bowel grade 1: 25%, rectal grade 1: 2% and bladder grade 1: 13%. One patient had grade 3 small bowel toxicity. The 3-year actuarial rate of grade 2 or greater toxicity, disease-free survival and overall survival rate were 3.3%, 84% and 90%, respectively. CONCLUSIONS: The preliminary analysis of IMRT for adjuvant treatment of endometrial carcinoma shows excellent local control and low toxicity. However, longer follow-up and more patients are needed to ascertain whether the benefits of IMRT treatment seen here translate into long-term reductions in toxicities and local recurrence.     

The combined operative and radiotherapeutic treatment (CORT) of recurrent tumors infiltrating the pelvic wall: first experience with 18 patients.

CORT is a new radiosurgical treatment concept for patients with recurrent gynecologic malignancies infiltrating the pelvic wall. The operative part consists of (i) staging laparotomy; (ii) maximum debulking of the tumor from the pelvic wall and exenteration of infiltrated central pelvic organs; (iii) implantation of brachytherapy guiding tubes on the residual tumor/tumor bed at the pelvic wall; (iv) pelvic wall plasty with muscle and omentum flaps to create a protective distance between the tubes and the pelvic hollow organs and to induce therapeutic angiogenesis; and (v) surgical reconstruction of bowel, bladder, and vulvoperineovaginal functions. Radiation is given postoperatively as fractionated HDR brachytherapy via the implanted tubes. Patients without prior pelvic radiation also receive preoperative whole pelvis teletherapy. Eighteen patients with recurrent malignancies infiltrating one pelvic wall have been treated with CORT in a prospective phase I/II trial at the University of Mainz. Fourteen patients had a history of radiation therapy with midpelvic doses of 40-100 Gy (median, 65 Gy) as primary treatment. Eleven patients (61%) are without evidence of disease at 6-32 months (median, 15 months) follow-up. Four patients have died from pelvic progression and distant metastases, and two patients are alive with disease after 12 months. There was no operative mortality; however, one patient succumbed from fatal thromboembolism 6 months after therapy. Three patients with prior radiation of greater than 75 Gy had to be treated for intestinal fistulas. We conclude that CORT is feasible with encouraging preliminary results.     

Whole-abdominal radiotherapy for patients with minimal residual epithelial ovarian cancer

Sixteen patients with advanced epithelial ovarian cancer who were treated with cytoreductive surgery followed by multiagent chemotherapy were found to have residual tumor masses less than 2 cm in greatest diameter at reexploration and were treated with whole-abdominal radiation (19-31 Gy). Thirteen patients also received pelvic boosts to a total pelvic dose of 41-53.7 Gy. Radiotherapy was completed in all but 2 patients after treatment delays in 7 patients. Early treatment complications included myelosuppression in 11 patients, diarrhea in 3, and a self-limited small bowel obstruction in one. Delayed complications were severe and included 9 patients with radiation enterocolitis, 8 of whom required intestinal resection or diversion. One additional patient with radiation cystitis required instillation of formalin to control bleeding. Two patients are without evidence of disease 28 and 30 months following radiotherapy, while the remaining 14 patients have recurred after a median progression-free interval of 9 months (range 1-30 months). All patients who recurred failed within the treatment field and died of cancer after a median interval of 19 months following radiotherapy and 9 months after documentation of progression. These data suggest that few patients with persistent ovarian cancer following surgery and chemotherapy will be salvaged with radiotherapy.     

Concurrent chemoradiotherapy using high-dose-rate intracavitary brachytherapy for uterine cervical cancer

OBJECTIVE: We retrospectively reviewed our experience with concurrent chemoradiotherapy (CCRT) using high-dose-rate intracavitary brachytherapy (HDR-ICBT) to assess its feasibility and efficacy in the treatment of patients with uterine cervical cancer. METHODS: Forty patients with uterine cervical squamous cell carcinoma treated with CCRT using HDR-ICBT were analyzed. The median cervical tumor size assessed by MRI was 63 mm (range: 40-86 mm). Eighteen patients (45%) had enlarged pelvic nodes on MRI (> or =10 mm). Cisplatin (20 mg/m2/day) was concurrently administered with radiotherapy for 5 days at 21-day intervals for a median of three courses (range: 1-5 courses). Thirty-eight (95%) patients received whole pelvic external beam radiotherapy (EBRT) with 40 Gy/20 fractions followed by HDR-ICBT with 18 Gy/3 fractions to point A. Subsequently, additional pelvic EBRT with 10 Gy/5 fractions was delivered with a midline block. The cumulative biological effective dose (BED) at point A of this schedule was 77 Gy10. The median follow-up period for all 40 patients was 37 months (range: 8-71 months). RESULTS: Grade 3/4 leukopenia was the most common acute side effect (83%). The actuarial 3-year pelvic control rate, disease-free survival rate, and overall survival rate were 91%, 67%, and 79%, respectively. Eight (20%) patients suffered late gastrointestinal complications (all grades). No patient suffered radiation cystitis (all grades). Only one patient experienced grade 3 complication (enterocolitis). The actuarial 3-year late complication rate (all grades) was 9% for proctitis and 15% for enterocolitis. CONCLUSION: This preliminary study suggests that CCRT using HDR-ICBT is feasible and efficacious for patients with locoregionally advanced uterine cervical cancer.     

Small cell of the ovary, hypercalcemic type -- analysis of combined experience and recommendation for management. A GCIG study

Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a rare tumor typically affecting young women. It is an aggressive malignancy with a poor prognosis and few long-term survivors. OBJECTIVE: Investigate the outcome of patients with SCCOHT. METHOD: Data were collected for patients with SCCOHT treated in Australia, Canada and Europe. Information included stage, surgery, chemotherapy, radiotherapy, recurrence and survival. RESULTS: The median follow-up is 13 months for all patients and 35.5 months in surviving patients. Ten patients had FIGO stage I tumors, six stage III tumors and one stage unknown. All underwent surgical resection. Adjuvant platinum-based chemotherapy was given to all patients. Seven received adjuvant radiotherapy with either pelvic and para-aortic radiotherapy, average dose 46.5 Gy (40 Gy/25# - 50.4 Gy/23#), or pelvic and whole abdominal radiotherapy, average dose 45 Gy to pelvis and 25 Gy (22.5 Gy/22# - 30 Gy/25#) to abdomen. The median survival for stage I tumors was not reached and was 6 months for stage III tumors. For the ten patients with stage I tumors: six received adjuvant radiotherapy with five alive and disease-free; four received no adjuvant radiotherapy with one alive and disease-free, while three have relapsed with one alive and disease-free after resection. Of the seven patients with stage III or unknown stage tumors, all but one have died. Recurrences were most frequent in the pelvis and the abdomen. Patients receiving salvage treatment with chemotherapy and radiotherapy did poorly. CONCLUSION: We advocate a multi-modality treatment approach including surgery, chemotherapy with the addition of radiotherapy either sequentially or concurrently.     

Radiation injury to intestine following hysterectomy and adjuvant radiotherapy for cervical cancer

OBJECTIVE: To evaluate the risk factors for nonrectal radiation-induced intestinal injury (NRRIII) following adjuvant radiotherapy (RT) for cervical cancer using a retrospective review of medical records. METHODS: From September 1992 to December 1998, 164 patients with uterine cervical cancer that had completed their allocated adjuvant radiotherapy at the Chinese Medical University Hospital were enrolled for NRRIII analysis. The patients were classified into two groups according to the extent of surgery. Group A consisted of 110 patients (International Federation of Gynecology and Obstetrics [FIGO] stage: IB, n = 87; IIA, n = 21; IIB, n = 2) undergoing radical hysterectomy and bilateral pelvic lymph node dissection, while Group B was composed of 54 analogs receiving adjuvant radiotherapy following incident extrafascial hysterectomy. Treatment consisted of external beam radiotherapy (EBRT) and high-dose-rate intravaginal brachytherapy (HDRIVB). Initially, the whole pelvis was treated with 10 MV X-rays. After irradiation (44 Gy in 22 fractions over 4-5 weeks), the field was limited to the true pelvis and a further 10-20 Gy delivered in 5-10 fractions. For 21 patients in group A without pelvic lymph node metastasis or lymphovascular invasion, the radiation field was confined to the lower pelvis, with a prescribed dose of 50-58 Gy delivered over 5-6 weeks. HDRIVB was performed using an Ir-192 remote after-loading technique at 1-week intervals. A total of 159 patients (97%) received two insertions, while 5 had only one. The standard prescribed HDRIVB dose was 7.5 Gy to the vaginal surface. Logistic regression analysis was performed for assessment of the factors associated with NRRIII. RESULTS: After 38-119 months of follow-up (median, 60), 22 patients (13.4%) developed Radiation Therapy Oncology Group (RTOG) grade 2 or greater NRRIII at a median latency of 18 months (range, 5-48). Four patients were diagnosed as grade 3 complications requiring surgery and three had expired. The independent factors for NRRIII were radical hysterectomy (P = 0.04, relative risk 2.45), lower-pelvic dose >54 Gy (P = 0.0001, relative risk 10.27), and age over 60 years (P = 0.001, relative risk 5.45). The incidence of NRRIII for patients receiving whole and lower-pelvic irradiation was 14.5% and 10.6%, respectively (P = 0.45). Although there was no statistical significance comparing the two external beam irradiation strategies in terms of NRRIII, all four patients with grade 3 NRRIII underwent whole pelvic irradiation. CONCLUSION: This study identifies three predictive factors for the development of NRRIII following adjuvant radiotherapy for cervical cancer. Limiting the EBRT dose to less than 54 Gy, meticulous patient selection in the elderly, careful planning of the irradiated field, and the constraint of vaginal brachytherapy are four approaches to optimization of postoperative adjuvant radiotherapy.     

Unilateral groin and pelvic irradiation for unilaterally node-positive women with vulval carcinoma

It is essential that any patient with resected vulval cancer and significant nodal disease receive optimal adjuvant treatment with radiation. Adequate radiotherapy for such patients with unilateral positive groin nodes has not been defined. Whether both groins and pelvic sidewalls should be irradiated or only the affected (node positive) side remains unclear. From our registry, we identified all patients with primary, previously untreated squamous cell carcinoma of the vulva undergoing bilateral inguinofemoral lymphadenectomy (superficial and deep nodes) and having unilaterally positive groin nodes treated with unilateral groin and pelvic radiotherapy (44 Gy in 22 fractions). Clinical and pathologic records were reviewed to identify the anatomical site and timing of recurrences in these patients and determine whether unilateral groin and pelvic irradiation was sufficient for disease control on the node-negative side. From 1983 to 2002, 20 patients with unilateral positive nodes treated with unilateral groin and pelvic irradiation were identified. Nineteen patients were classed as having FIGO stage III disease and one as FIGO stage IV due to involvement of the rectal mucosa. There were nine patients with disease recurrences in this group (45%). The disease-free interval ranged from 4 to 31 months (median time to recurrence, 9 months). All nine patients had local or regional failures, the most common site being the ipsilateral groin (six of nine patients). One patient was also found to have distant metastases. There were no recurrences noted in the contralateral (nonirradiated) groin or pelvic sidewall. Recurrence was generally fatal. Eight of the nine patients subsequently died of their disease. The ninth patient died of another cause. There was a high incidence of regional failure after unilateral groin and pelvic radiotherapy, but there were no recurrences on the nonirradiated, node-negative side. Although a small series, we speculate that there is no apparent disadvantage to administering unilateral adjuvant radiotherapy for unilaterally positive groin nodes and encourage further studies in order to more confidently determine whether the tendency observed in our center holds true.     

Interstitial Brachytherapy for Vaginal Recurrences of Endometrial Carcinoma

OBJECTIVE: The aim of this study was to evaluate the efficacy of interstitial brachytherapy in the management of vaginal recurrences of endometrial carcinoma. METHODS: Thirty patients received interstitial irradiation, with or without external beam radiotherapy. They were followed for a minimum of 5 years or until death. RESULTS: The median age was 66 years at initial diagnosis of endometrial cancer. FIGO stages included Stage I (n = 18), Stage II (n = 7), and Stage III (n = 5). All patients were treated originally by total abdominal hysterectomy and bilateral salpingo-oophorectomy, with or without lymphadenectomy, and 13 (43%) also received postoperative adjuvant whole pelvis radiotherapy as part of their primary treatment. Vaginal recurrences were diagnosed at a mean interval of 29 months after hysterectomy (range, 3-119 months). No patient had clinical evidence of pelvic sidewall extension or of distant metastatic disease. All patients were treated with interstitial brachytherapy; each implant delivered a mean maximal tumor dose of 25.5 Gy. Eighteen patients (60%) also received external beam radiotherapy (mean dose, 48 Gy) as part of their treatment for vaginal recurrence. Twenty-eight patients (93%) experienced a complete clinical response. Ten patients relapsed in the vagina (n = 5) or at distant sites (n = 5). Eleven patients are dead of disease. From the time of vaginal recurrence, the median overall survival was 60 months and the cause of death adjusted 5-year survival rate was 65%. Major morbidity included radiation proctitis (n = 2), fistula (n = 2), and radiation stricture (n = 1). CONCLUSION: Interstitial irradiation resulted in favorable local control as well as a 5-year survival rate and morbidity comparable to that reported previously for conventional brachytherapy.     

Chemotherapy versus radiotherapy versus observation for high-risk cervical carcinoma after radical hysterectomy: A randomized, prospective, multicenter trial.

BACKGROUND: Adjuvant treatment modalities after radical hysterectomy have long been used in an attempt to eradicate microscopic tumor residuals in patients at high risk for recurrence. However, it has not been clearly demonstrated that adjuvant radiation, adjuvant chemotherapy, or both improve the outcome. To evaluate the effect of adjuvant treatment in patients with high-risk cervical cancer after radical hysterectomy, the Austrian Gynecologic Oncology Group conducted a prospective, randomized, multicenter clinical trial between 1989 and 1995. MATERIAL AND METHODS: Seventy-six patients with stage IB-IIB cervical cancer treated with radical hysterectomy with pelvic lymph node metastases and/or vascular invasion randomly received adjuvant chemotherapy (400 mg/m2 carboplatin, and 30 mg bleomycin), standardized external pelvic radiation therapy, or no further treatment. RESULTS: After a median follow-up of 4.1 years (range, 2-7) there were no statistically significant differences (P = 0.9530) in disease-free survival among the three treatment arms. CONCLUSION: The data suggest that adjuvant chemotherapy or radiation do not improve survival or recurrence rates in high-risk cervical cancer patients after radical hysterectomy. The most important treatment for these patients seems to be radical abdominal hysterectomy with systematic pelvic lymphadenectomy.     

Adjuvant chemotherapy with paclitaxel and carboplatin in non-endometrioid carcinoma of the uterus

PURPOSE OF INVESTIGATION: Uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) represent more aggressive tumors than the more common endometroid cancers, exhibiting a propensity for distant metastasis. The aim of this study was to investigate the activity and safety of paclitaxel/carboplatin chemotherapy as the only adjuvant treatment in patients with surgically resected UPSC and UCCC. METHODS: Fifteen patients with Stage IB-IV UPSC or UCCC were treated with a mean of six courses of paclitaxel 175 mg/m3 plus carboplatin AUC 5 at three-week intervals, three to six weeks after undergoing surgery with curative intent. No patient had residual disease after surgery and none underwent pre- or post-chemotherapy irradiation. RESULTS: With a median follow-up of 29.4 months, six patients (40%) relapsed and two (13%) died of disease. Mean time to recurrence was 16.9 months. Recurrence rate per Stage was 17% for Stage IB/C, 57% for Stage IIIA/C and 50% for Stage IV. Projected 5-year overall survival and progression-free survival was 79.7% and 55.7%, respectively. All relapses were abdominopelvic whereas in one case pelvic recurrence was accompanied by lung metastasis. The most frequent grade 3-4 toxicity was neutropenia. CONCLUSION: Chemotherapy with paclitaxel plus carboplatin is feasible and possibly prevents distant metastasis when used as adjuvant in UPSC and UCCC.     

Whole abdominal radiotherapy following second-look laparotomy for ovarian carcinoma.

AIM: The safety and efficacy of whole abdominal radiotherapy was evaluated as salvage or consolidation treatment for ovarian cancer patients treated with primary surgery and chemotherapy, followed by second-look laparotomy (SLL). Overall survival and acute and late toxicity of treated patients were assessed. METHODS: Patients were recruited between April 1981 and June 1994. All patients had SLL performed at Royal Prince Alfred Hospital after completion of primary chemotherapy. Data collected included demographic details, diagnosis, tumor stage, histology, grade, adjuvant chemotherapy, and radiotherapy. Radiation dose and fractionation, field size, boost volume and dose, failure to complete treatment and treatment interruptions, renal dose, and acute and late toxicity were recorded. RESULTS: Fifty-one patients were evaluated; the median age was 51 years. Median follow-up for patients still alive was 62 months. Prior to 1988, chemotherapy comprised oral chlorambucil, with or without cisplatin (n = 25), while after this date all patients (n = 26) received primary cisplatin-based therapy. A radiation dose of 22. 5 Gy over 22 fractions was planned to the whole abdomen followed by a pelvic boost of 22 Gy in 11 fractions. Radiotherapy was completed in 37 (73%) patients. Treatment interruptions were necessary in 12 (24%) patients. Thrombocytopenia, neutropenia, nausea, vomiting, and diarrhea were the main causes of incomplete or interrupted treatment. Late bowel toxicity was seen in 6 (12%) patients, 2 of whom required laparotomy to relieve obstruction. There were no treatment-related deaths. Seven of the 51 patients are alive and free of disease, 2 died from other causes, and 2 are alive with evidence of recurrent or progressive disease. Mean follow-up time for surviving patients is 78.5 months. Overall survival at 2, 5, and 10 years was 65, 27, and 10%, respectively. Residual disease after primary surgery, smaller preirradiation tumor residuum, and completion of radiotherapy were independently associated with improved overall survival. CONCLUSION: In this poor-prognosis group of patients, a combined approach of surgery, chemotherapy, and radiotherapy, while associated with acceptable toxicity, may not afford a prolongation of survival.     

10-Gy single-fraction pelvic irradiation for palliation and life prolongation in patients with cancer of the cervix and corpus uteri.

OBJECTIVE: The goal of this study was to evaluate the effects of single fractions of 10 Gy pelvic irradiation for palliation and life prolongation in patients with cancer of the uterine cervix or corpus. METHODS: A retrospective analysis was performed on 37 cervical cancer and 27 corpus cancer patients treated in the period 1988-1998. All patients had a life expectancy of less than 1 year. Due to stage of disease, age (median 82 years), or comorbidity they were considered unapt for surgery or conventional radiotherapy. Eleven patients with recurrence within irradiated field or early progression received one, 51 patients received two, and 2 patients received three fractions with a 4-week interval. RESULTS: Vaginal bleeding stopped in 90% and malodorous discharge in 39% of the patients. Among 46 patients with advanced disease treated for palliation, 10 (22%) showed complete tumor responses. Median time to progression was 6 months, and median survival, 9 months. Eighteen patients with early-stage disease and serious comorbidity were treated with life prolongation and symptom prevention as intention, and showed seven complete responses. Median survival was 13 months, and half the deaths were caused by intercurrent disease. Median hospital stay was 5 days and rehabilitation was easy. Fifty-six percent of the patients experienced no acute side effects and 33% had minor gastrointestinal problems. Three patients (6%) had serious late bowel complications, one with a fatal outcome, the symptoms appearing 9-10 months posttreatment. CONCLUSION: The 10-Gy single-fraction pelvic radiation regimen is an effective means of symptom palliation and is well tolerated. Tumor responses are obtained. The risk of late bowel complications is a concern for patients with a life expectancy greater than 9 months.

Complications of pelvic radiation therapy for gynecologic malignancies in elderly women

The purpose of this study was to determine the frequency and severity of complications following pelvic irradiation in elderly women with gynecologic malignancies. A retrospective analysis was conducted of the 60 women over 65 years of age treated with pelvic radiation therapy for cervical (26), endometrial (31) or proximal vaginal (3) cancer at the UCLA Medical Center between 1978 and 1991. Acute grade 3 to 4 gastrointestinal (GI) complications, using Gynecologic Oncology Group (GOG) criteria occured in three of 60 patients (5%). Chronic complications occured in 28 of 49 patients (57%) followed for longer than 3 months after radiation therapy. The 3-year actuarial rate of chronic GI and/or genitourinary (GU) complications was 63% for any grade and 24% for grades 2,3 or 4. Twelve of the 14 grade 2–4 chronic complications were GI. The 3-year actuarial chronic complication rate was 45% for GI compared to 17% for GU ( P = 0.01). The median time to occurrence for GI and GU chronic complications was 8 and 19 months, respectively. In multivariate analysis, two or more pre-existing medical problems ( P = 0.03) and dose of external beam radiation therapy 45 Gy ( P = 0.07) were associated with the development of a chronic complication. We conclude that moderate to severe intestinal complications are common after pelvic irradiation of elderly women, particularly those with two or more pre-existing medical problems. Pelvic radiation therapy should be used judiciously in elderly women.     

Outcomes after definitive re-irradiation with 3D brachytherapy with or without external beam radiation therapy for vaginal recurrence of endometrial cancer

BackgroundLimited outcome data exists on salvage re-irradiation for vaginal relapse of previously-irradiated endometrial cancer. We report our 10-year experience with management of vaginal recurrence using definitive intent re-irradiation brachytherapy with or without EBRT.MethodsA retrospective review was performed on 22 patients treated with definitive-intent re-irradiation brachytherapy ± EBRT for vaginal recurrence of endometrial cancer. The cumulative rectosigmoid and bladder D2cc (EQD2) were limited to <75 Gy and <90 Gy, respectively. Kaplan-Meier and Cox proportional hazards modeling were used to estimate survival. Severe (grade 3 or higher) radiation-related toxicities, defined according to CTCAE v4, were recorded.ResultsPrior radiation therapy consisted of vaginal brachytherapy (54.5%), pelvic EBRT (22.7%), or combination pelvic EBRT and brachytherapy (22.7%). Median re-irradiation interval was 26.6 months. Salvage re-irradiation consisted of EBRT with brachytherapy in 50.0% and brachytherapy alone in 50.0%. Median HR-CTV D90 (EQD2) was 64.5 Gy (IQR: 49.6–75.8). Median cumulative D2cc for bladder, rectum, and sigmoid were 72.1 Gy (range: 30.3–81.8), 70.6 Gy (range: 32.0–80.5), and 52.7 Gy (range: 29.6–75.3), respectively. At a median follow-up of 27.6 months, 3-year local control, regional control, disease-free survival, and overall survival rates were 65.8%, 76.6%, 40.8%, and 68.1%, respectively. There were no grade ≥ 3 acute or late rectosigmoid or bladder toxicities.ConclusionRe-irradiation with 3D conformal brachytherapy for vaginal recurrence is feasible and safe as long as cumulative dose to surrounding normal organs is limited, and offers a chance to potentially salvage 40% of patients presenting with vaginal recurrence in the setting of prior pelvic radiation.
