PurposeThe objective of the study was to determine the impact of brachytherapy implant quality on outcome among cervical cancer patients treated on Radiation Therapy Oncology Group prospective trials 0116 and 0128.MethodsAll enrolled patients received concurrent chemoradiation followed by brachytherapy. Individual brachytherapy parameters, including the symmetry of ovoids in relation to the tandem, displacement of ovoids in relation to the cervical os, tandem bisecting the ovoids, tandem in the midpelvis, and appropriateness of packing, were scored for each implant. Multivariate Cox proportional hazards models were constructed for each parameter for local recurrence (LR), regional recurrence, distant recurrence, disease-free survival (DFS), and overall survival.ResultsRecords for 103 patients were analyzed. The median follow-up time was 24.5 months. Patients with unacceptable symmetry of ovoids to the tandem had a significantly higher risk of LR than patients in the acceptable group (hazard ratio [HR], 2.67; 95% confidence interval [CI], 1.11–6.45;P= 0.03). Patients with displacement of ovoids in relation to the cervical os had a significantly increased risk of LR (HR, 2.50; 95% CI, 1.05–5.93;P= 0.04) and a lower DFS rate (HR, 2.28; 95% CI, 1.18–4.41;P= 0.01). Inappropriate placement of packing resulted in a lower DFS rate (HR, 2.06; 95% CI, 1.08–3.92;P= 0.03).ConclusionsAssessment of the quality of a brachytherapy implant is imperative, as proper placement has an impact on patient DFS. If feasible, inappropriate placements should be corrected before treatment initiation. Brachytherapy applicators for cervical cancer should preferably be placed and assessed by experienced practitioners.

PURPOSE Although androgen suppression results in a tumor response/remission in the majority of patients with carcinoma of the prostate, its potential value as an adjuvant has not been substantiated. MATERIALS AND METHODS In 1987, the Radiation Therapy Oncology Group (RTOG) initiated a randomized phase III trial of adjuvant goserelin in definitively irradiated patients with carcinoma of the prostate. A total of 977 patients had been accessioned to the study. Of these, 945 remained analyzable: 477 on the adjuvant arm and 468 on the observation arm. RESULTS Actuarial projections show that at 5 years, 84% of patients on the adjuvant goserelin arm and 71% on the observation arm remain without evidence of local recurrence (P < .0001). The corresponding figures for freedom from distant metastases and disease-free survival are 83% versus 70% (P < .001) and 60% and 44% (P < .0001). If prostate-specific antigen (PSA) level greater than 1.5 ng is included as a failure (after > or = 1 year), the 5-year disease-free survival rate on the adjuvant goserelin arm is 53% versus 20% on the observation arm (P < .0001). The 5-year survival rate (for the entire population) is 75% on the adjuvant arm versus 71% on the observation arm (P = .52). However, in patients with centrally reviewed tumors with a Gleason score of 8 to 10, the difference in actuarial 5-year survival (66% on the adjuvant goserelin arm v 55% on the observation arm) reaches statistical significance (P = .03). CONCLUSION Application of androgen suppression as an adjuvant to definitive radiotherapy has been associated with a highly significant improvement in local control and freedom from disease progression. At this point, with a median follow-up time of 4.5 years, a significant improvement in survival has been observed only in patients with centrally reviewed tumors with a Gleason score of 8 to 10.

ObjectiveThe primary objective of the study was to compare the survival rate of patients who had received neoadjuvant chemotherapy with that of patients who had received radiation therapy for stage IIB cervical cancer. The secondary objective was to analyze the effect of neoadjuvant chemotherapy on pathological prognostic factors.Materials and MethodsWe retrospectively reviewed the medical records of patients who had received therapy for stage IIB cervical cancer. Based on the primary therapy, 192 patients were divided into 2 groups; patients in the neoadjuvant chemotherapy group (n =103) underwent a type III radical hysterectomy after completion of the neoadjuvant chemotherapy. Patients in the other group (n = 89) were treated with radiation alone or a combination of chemotherapy and radiotherapy.ResultsAfter neoadjuvant chemotherapy, the level of squamous cell carcinoma antigen, tumor size, lymph node involvement, and parametrium involvement were significantly decreased. However, 90.3% of the patients who had received neoadjuvant chemotherapy needed to have adjuvant therapy after radical surgery because of poor pathological prognostic factors. The rate of disease-free survival did not differ significantly between the 2 groups. However, the overall survival rate was significantly lower in the neoadjuvant chemotherapy group for patients who were 60 years or older (P = 0.03). The rates of disease-free survival and overall survival for patients who had a good (complete or partial) response to the neoadjuvant chemotherapy were not significantly higher than the rates for patients in the radiation therapy group.ConclusionsAlthough neoadjuvant chemotherapy improved pathological prognostic factors in patients with stage IIB cervical cancer, it was not sufficiently effective to decrease adjuvant therapy. Neoadjuvant chemotherapy also did not improve the rate of patient survival compared to the rate of patient survival in the radiation therapy group.

16004 Aims: To determine the impact of the c-erb-B2 overexpression receptor on pelvic relapse and on disease-free survival (DFS) in patients with advanced cervical cancer receiving concurrent chemo-radiotherapy. Methods: One hundred thirty six patients with advanced cervical cancer (stage: 12 IB2-IIA, 34 IIB, 71 IIIB, 19 IVA); histology: 86 epidermoid and 14 adenocarcinoma) were analyzed to detect c-erbB-2 level using an immunohistochemical method (Herceptest Dako). Cases c-erbB-2 (+3) were considered positive. All patients received pelvic radiotherapy, brachitherapy and concurrent chemotherapy with two schedules: 48 patients with tegafur (800 mg/day via oral) and 88 with tegafur (same doses) plus five cycles of weekly cisplatin 40 mg/m2/week iv. Results: Of the 136 biopsies, 32 (23.5%) were c- erbB-2 positive. The disease free survival to 3 and 5 years of the patients were 61% and 58% for c-erb-B2 negative and 36% and 36% for c-erb- B2 positive (p=0.02), respectively.We divided our patients in four groups: c-erb-B2 positive treated with cisplatin; c-erb-B2 positive without cisplatin, c-erb-b2 negative treated with cisplatin and c-erb-b2 negative without cisplatin. The group of patients with c-erb-B2 overexpression that did not received platinum treatment had a higher rate of pelvis relapse (p<0.0001) and with a decreased DFS (p=0.0014). Conclusions: c-erbB-2 overexpression may imply a poor prognosis for patients with advanced cervix cancer, especially if they did not receive concurrent radiochemotherapy with cisplatin.

Background: Standard treatment for locally advanced cervical cancer is external beam radiotherapy followed by brachytherapy (BT). Stereotactic body radiation therapy (SBRT) is a possible option for treating patients ineligible for BT. Patients and Methods: From October 2012 to July 2020, nine women with cervical cancer received SBRT to high-risk volumes. The Kaplan–Meier method was used to estimate the rates of overall and disease-free survival. Results: The median age was 52 years; 88% of patients had squamous carcinoma. Reasons for forgoing BT were cervical canal stenosis, treatment refusal and hematological disease. The median boost dose was 18 Gy and the median dose per fraction was 6 Gy. Median follow-up was 16 months. The median survival was 24 months, the actuarial 2-year OS rate was 70%, and median disease-free survival was 11 months. One grade 3 late vaginal toxicity was reported. No acute nor late grade 4 toxicities were observed. Conclusion: SBRT boost in patients with cervical cancer ineligible for BT led to acceptable survival outcomes and a safe toxicity profile.

5531 Background: To determine the impact of NACT on surgical debulking rate, overall and disease-free survival and quality of life (QOL) in patients with advanced EOC. Methods: Between Oct 2001 and Dec 2006, 128 previously untreated EOC patients (median age- 50 years, range 30 to 65) with FIGO stage III C & IV (pleural effusion only) have been randomized into - Arm A (n=65) upfront debulking Surgery followed by 6 cycles of Paclitaxel & carboplatin (PC) and Arm B (n=63): NACT with 3 cycles of PC followed by debulking Surgery then 3 more cycles. Eligibility criteria include - age 18 to 65 years, biopsy / cytological proven EOC, adequate hematological, renal, liver & cardiac functions, normal upper & lower GI endoscopy & CEA levels. Both groups were compared for debulking rate, duration of surgery, blood loss, intra & postoperative morbidity & mortality, overall response to treatment and QOL (FACT- O questionnaire). Results: 100 of 128 patients have completed treatment (arm A- 56, B-44). 7 patients were not evaluable; (Germ cell tumor-1, mixed Mullerian tumor-2, dual primary-1 and krukenburg-3). 93 patients are evaluable. Patients’ characteristics are similar in both arms. Grade III-IV - GIT (3% vs. 4%) & bone marrow (9% Vs 7%, p=ns) toxicity was similar in arm A & B, among 463 CT cycles administered. Patients in NACT arm had higher optimum debulking rate, p<. 0001, decreased blood loss during surgery (mean vol 520 vs 373 ml p<0.003) and reduced postoperative infections 14.8 % vs. 2.5%, p<0.04. Mean operative time (110 vs 95 minutes, p=0.12) and hospital stay (12 Vs 9.4 days, p=0.1) were similar in arm A & B. The median overall survival (arm A & B: 42 vs 29 months, p=0.07) and disease free survival (20 vs 25 months, p=0.11) is not different at a median follow up of 41 months. QOL score was significantly better in NACT arm at the end of treatment. (93 vs 114, p<. 001). Conclusions: Neoadjuvant chemotherapy in advanced epithelial ovarian cancer is associated with higher optimum debulking rate with reduced postoperative morbidity and improved quality of life.

e16520 Background: Recently, the rates of obese and overweight patients have increased dramatically. However, the effect of body mass index (BMI) have not been evaluated in treatment outcomes for patients with advanced stage cervical cancer receiving definitive chemotherapy and radiation therapy, and is the purpose of this study. Methods: After obtaining approval from the Washington University Human Studies Protection Office, a retrospective cohort study (n = 321) was performed on all cervical cancer patients with stage IB1 with positive lymph nodes or ≥ stage IB2 from January 1998 to January 2008. The median duration of follow up was 60 months. BMI was calculated using the National Institute of Health online BMI calculator. Main outcomes were overall survival, disease free survival, and radiation complications such as radiation enteritis/cystitis, bowel obstruction, and fistula formation. Univariate and multivariate analyses were performed, and Kaplan-Meier curves were generated. Results: Underweight patients (BMI<18.5 kg/m2) compared to normal weight (BMI = 18.5–25 kg/m2) and overweight/obese (>25 kg/m2) have a higher actuarial complication rate (p = 0.0137). Regardless of weight there is no difference in disease free survival. However, underweight patients have a significantly poorer overall survival than those patients with a higher BMI (>18.5 kg/m2) (p < 0.001). Conclusions: Underweight patients have a diminished overall survival compared to normal or obese cervical cancer patients. This is of clinical relevance when counseling underweight cervical cancer patients who will be cured of the disease with chemotherapy and radiation therapy, but have a significant risk of suffering potentially fatal complications from treatment. Further study needs to be done to elucidate this relationship further. No significant financial relationships to disclose.

PURPOSE A prospective study was performed to determine the outcome of patients with esophageal cancer who received preoperative radiation therapy and chemotherapy followed by esophagectomy, and to determine the role of preresection esophagogastroduodenoscopy (EGD) in predicting the patients in whom surgery could possibly be omitted, and the impact of surgery on survival. MATERIALS AND METHODS Thirty-five patients with localized carcinoma of the esophagus received concurrent external-beam radiotherapy and chemotherapy followed by esophagectomy. Patients received 45 Gy in 25 fractions. Chemotherapy consisted of continuous infusion fluorouracil (5-FU; 1,000 mg/m2/d) on days 1 through 4 and 29 through 32 and cisplatin (100 mg/m2) on day 1. Patients underwent an Ivor-Lewis esophagectomy 18 to 33 days after completion of radiotherapy. RESULTS Eighty percent of the patients had squamous cell carcinoma and 20% had adenocarcinoma. In addition, 51% had a pathologic complete response (CR). Twenty-two of the 35 underwent a preresection EGD before resection. Seventeen of the 22 (77%) had negative pathology from the preresection EGD, but seven of the 17 (41%) had residual tumor at surgery. The median survival and disease-free survival rates for all patients were 25.8 months and 32.8 months, respectively. Eighteen patients (51%) had no tumor at resection. The median survival for these patients was 36.8 months; the median disease-free survival time has not been reached. The median survival and disease-free survival rate for the patients with residual tumor in the surgical specimen were 12.9 months and 10.8 months, respectively. CONCLUSION Preresection EGD is not reliable for determining the presence of residual disease or the patients in whom surgery could be omitted. Twenty-five percent of the patients with residual tumor in the resected surgical specimen were long-term survivors; this suggests a benefit from esophagectomy after concurrent radiotherapy and chemotherapy.
