PURPOSE: To determine the long-term results of a Phase II trial of perioperative high-dose-rate brachytherapy (PHDRB) in primary advanced or recurrent gynecological cancer. METHODS AND MATERIALS: Fifty patients with locally advanced and recurrent gynecological cancer suitable for salvage surgery were included. Unirradiated patients (n = 25) received preoperative chemoradiation followed by surgery and PHDRB (16-24 Gy). Previously irradiated patients (n = 25) received surgery and PHDRB alone (32-40 Gy). RESULTS: Median followup was 11.5 years. Eight unirradiated patients (32%) developed Grade >= 3 toxic events including two fatal events. Local and locoregional control rates at 16 years were 87.3% and 78.9%, respectively. Sixteen-year disease-free and overall survival rates were 42.9% and 46.4%, respectively. Ten previously irradiated patients (40.0%) developed Grade >= 3 adverse events, including four fatal events. Local and locoregional control rates at 14 years were 59.6% and 42.6%, respectively. Fourteen-year disease-free and overall survival rates were 16.0% and 19.2%, respectively. CONCLUSIONS: PHDRB allows effective salvage of a subset of unfavorable gynecological tumors with high-risk surgical margins. Toxicity was unacceptable at the initial dose levels but deescalation resulted in the absence of severe toxicity without a negative impact on locoregional control. A substantial percentage of patients remain alive and controlled at >10 years including a few previously irradiated cases with positive margins. (C) 2018 American Brachytherapy Society.

Purpose: To assess the safety, feasibility, and efficacy of free-hand intraoperative multicatheter breast implant (FHIOMBI) and perioperative high-dose-rate brachytherapy (PHDRBT) in early breast cancer. Methods and Materials: Patients with early breast cancer candidates for breast conservative surgery (BCS) were prospectively enrolled. Patients suitable for accelerated partial breast irradiation (APBI) (low or intermediate risk according GEC-ESTRO criteria) received PHDRBT (3.4 Gy BID × 10 in 5 days). Patients not suitable for APBI (high risk patients according GEC-ESTRO criteria) received PHDRBT boost (3.4 Gy BID × 4 in 2 days) followed by whole breast irradiation. Results: From June 2007 to November 2014, 119 patients were treated and 122 FHIOMBI procedures were performed. Median duration of FHIOMBI was 25 minutes. A median of eight catheters (range, 4-14) were used. No severe intraoperative complications were observed. Severe early postoperative complications (bleeding) were documented in 2 patients (1.6%), wound healing complications in 3 (2.4%), and infection (mastitis or abscess) in 2 (1.6%). PHDRBT was delivered as APBI in 88 cases (72.1%) and as a boost in 34 (27.8%). The median clinical target volume T was 40.8 cc (range, 12.3-160.5); median D90 was 3.32 Gy (range, 3.11-3.85); median dose homogeneity index was 0.72 (range, 0.48-0.82). With a median followup of 38.4 months (range, 8.7-98.7) no local, elsewhere, or regional relapses were observed; there was only one distant failure in PHDRBT boost. No major (acute or late) RTOG grade 3 or higher were documented in any of the 119 patients treated with PHDRBT. Cosmetic outcome in APBI patients was excellent or good in (87.0%) and fair or poor in (11.9%) while in boost patients was excellent or good in (76.4%) and fair in (23.5%). Conclusion: The FHIOMBI-PHDRBT program does not add complications to conservative surgery. It allows precise selection of APBI patients and offers excellent results in disease control and cosmetics. It also offers logistic advantages because it dramatically shortens the time of local treatment and avoids further invasive procedures.

Background: Amplification of the HER-2 gene occurs in 20% of breast cancer (BC) patients (pts). Trastuzumab administered concurrently with chemotherapy (CT) is the standard of care in the neoadjuvant setting. Moreover, the use of a combination of antiHER2 therapies with CT are related to an increased pCR, which could be a surrogate marker for survival. Methods: We retrospectively analyzed three historic cohorts with overexpressing HER2 BC. They received neoadjuvant CT based on dose dense anthracyclines followed by three schedules of antiHER2 therapy: 1) docetaxel plus trastuzumab (DT; n = 33 pts); 2) DT plus CBDCA (DTP; n = 17 pts); and 3) DT plus double blockade with triweekly pertuzumab or daily L (750mg/day; n = 12) (DTD; n = 14) before surgery. Study endpoints were safety, pCR (breast + axilla) based on Miller&Payne criteria and DFS. Results: Sixty-four pts with HER2 overexpressing BC were studied since 2005. Baseline characteristics were well balanced. The median age was 48 (range 23-80). Coexpression of ER and HER2 in each cohort was 48% in DT, 53%% in DTP and 57% DTD (p = 0.855) as well as initial BC stages (p = 0.64). Grade 3-4 toxicity in DT, DTP and DTD were respectively: asthenia 0%, 5.8% and 0% (p = 0.71), hand-foot syndrome 3%, 5.8% and 0% in DT, DTP and DTD (p = 0.719), anemia 0%, 5.8% and 0% (p = 0.71) leukopenia 6%, 11.7% and 0% in DTD (p = 0.60) and diarrhea in 35.7% in DTD (p = 0.002). We did not find differences in pCR (42.4% in the DT, 29.4%% in the DTP and 42.8% in DTD cohorts; p = 0.67), axillar response (type D) was significantly superior in the DTD cohort with the followed distribution of 51.1%, 52.9% and 85.7% respectively (p = 0.04). However breast responses were similar in the three cohorts (p = 0.9). With a median follow-up of 72, 90 and 21 months respectively, the number of pts who progressed were 12.1%, 11.7% and 0% in DT, DTP and DTD. Conclusions: We did not find differences in pCR in any cohort. The best significant axillary responses were in the DTD cohort, however this fact did not impact in total pCR. DTD cohort has more gastrointestinal toxicity. To date, median survival has not been reached.

Purpose Capecitabine is effective against metastatic breast cancer (MBC). We hypothesized that sequential treatment with dose-dense epirubicin/cyclophosphamide (EC) and docetaxel/capecitabine would be active and tolerable in the adjuvant/neoadjuvant setting. Methods In this prospective phase II clinical trial patients with HER2-negative and node-positive or locally advanced tumors were eligible to receive four cycles of EC (100/600 mg/m2) every 2 weeks with G-CSF on days 3¿10, followed by four cycles of docetaxel/capecitabine (75/1,000 mg/m2 b.i.d., days 1¿14) every 3 weeks. Results Fifty-five patients were enrolled with median age of 49, and 80% had hormone receptor-positive disease. The median tumor size was 2.5 cm, with a median of two axillary nodes involved. Seventy-five percent of the first 20 patients had grade 2/3 hand-foot syndrome (HFS). Dose reduction of capecitabine to 800 mg/m2 reduced the grade 2/3 HFS incidence to 31% in the remaining patients. No grade 4/5 toxicities were observed. All 20 patients treated preoperatively responded, with 5 (25%) pathologic complete responses and 3 additional pT0N1 tumors. At a median follow-up of 48 (range 28¿60) months, the event-free and overall survival rates are 91 and 98%, respectively. Conclusions Sequential treatment with dose-dense EC followed by docetaxel/capecitabine, using a lower capecitabine dose than that approved for MBC, has an acceptable toxicity profile and encouraging activity when used as neoadjuvant or adjuvant treatment of breast cancer.

Objectives: This study was undertaken to determine the tolerability of a 7-week schedule of external beam radiation therapy, high-dose-rate brachytherapy, and weekly cisplatin and paclitaxel in patients with locally advanced carcinoma of the cervix. Methods: Twenty-nine patients with International Federation of Gynecology and Obstetrics stages IB2 to IVa cervical cancer were treated with 40 mg/m2 per week of intravenous (i.v.) cisplatin and 50 mg/m2 per week of i.v. paclitaxel combined with 45 Gy of pelvic external beam radiation therapy and 30 Gy of high-dose-rate brachytherapy. Results: Eleven patients (37.9%) were able to complete the 6 scheduled cycles of chemotherapy. The median number of weekly chemotherapy cycles administered was 5 (range, 2-7). Thirty-five (20.1%) of 174 cycles of chemotherapy were not given because of toxicity. The median dose intensity of cisplatin was 31 mg/m2 per week (95% confidence interval [CI], 25.2-36.8); that of paclitaxel was 44 mg/m2 per week (95% CI, 39.9-48.3). Twenty-two patients (78.6%) were able to complete the planned radiation course in less than 7 weeks. Median radiation treatment length was 45 days (95% CI, 43.4-46.6). After a median follow-up of 48 months, 7 patients (24.1%) experienced severe (Radiation Therapy Oncology Group grade 3 or higher) late toxicity. No fatal events were observed. Seven patients have failed, 1 locally and 6 at distant sites. The 8-year local/pelvic control rate was 95.7%, and the 8-year freedom from systemic failure rate was 76.1%. Eight-year actuarial disease-free survival and overall survival were 63.1% and 75.9%, respectively. Conclusions: This study demonstrated unacceptable toxicity of combining the stated doses of concurrent cisplatin and paclitaxel chemotherapy with definitive radiotherapy for patients with advanced cervical cancer. Additional phase I/II trials are recommended to clearly establish the recommended phase II dose for these drugs.
