Title: Retrospective Analysis of Locally Advanced Noninflammatory Breast Cancer From Chennai, South India, 1990-1999

Abstract

Purpose: This was a retrospective observational study to elicit the outcome of the therapeutic strategy of concurrent neoadjuvant chemoradiotherapy protocol for locally advanced breast cancer. Methods and Materials: A large series of 1,117 consecutive cases of locally advanced breast cancer treated at the Cancer Institute (WIA), in Chennai, South India, between 1990 and 1999 and followed through 2004 formed the basis for this study. Disease-free survival was the main outcome, and nodal and tumor downstaging were the intermediate outcome measures studied. Results: Primary tumor downstaging was observed in 45% and nodal downstaging in 57.5%. The disease-free survival rate of nodal downstaged patients at 5, 10, and 15 years was 75%, 65%, and 58%, respectively. The corresponding rates for pre- and postoperative node-negative patients were 70%, 60%, and 59%. The best survival was seen among those who were tumor and node negative postoperatively. Nodal downstaging halved the risk of disease recurrence and death compared with node positivity, irrespective of tumor sterility. Conclusions: A randomized trial using cyclophosphamide, methotrexate, and 5-fluorouracil vs. an anthracycline-based regimen in the setting of concurrent chemoradiotherapy appears indicated. Additional preoperative chemotherapy to maximize nodal and tumor downstaging should be investigated. A change in postoperative chemotherapy according tomore » nodal status could also be explored.« less

  • Purpose: To retrospectively investigate the therapeutic results of arterial injection therapy by way of the superficial temporal artery for 88 cases of Stage III and IV (M0) tongue cancer and to clarify the factors that affected the therapeutic results. Methods and Materials: We administered intra-arterial chemoradiotherapy by continuous infusion of carboplatin in 39 patients between January 1993 and July 2002. Systemic concurrent chemotherapy was given to 19 of these patients. We administered intra-arterial chemoradiotherapy with cisplatin with sodium thiosulfate to 49 patients between October 2002 and December 2006. Concurrent systemic chemotherapy was given to 38 of these patients. Results: Themore » 3-year local control rate was 72% (T2-T3, 80%; and T4, 48%), and the 3-year survival rate was 57% (Stage III, 67%; Stage IV, 43%). On univariate analysis, age, T stage, N stage, overall stage, systemic chemotherapy, difference in intra-arterial chemotherapy, and performance status had a significant effect on survival. On multivariate analysis, N stage, systemic chemotherapy, difference in intra-arterial chemotherapy, and artery selected had a significant effect on survival. Conclusions: The therapeutic results of intra-arterial chemoradiotherapy using the superficial temporal artery were not inferior to the results of surgery. In particular, the results of arterial injection therapy using cisplatin with sodium thiosulfate were excellent, and we believe it will be a new therapy for advanced tongue cancer.« less
  • Purpose: Trastuzumab (Herceptin), an anti-human epidermal growth factor receptor 2 (HER2) antibody, has been shown to be an effective radiosensitizer in preclinical studies. The present Phase II trial evaluated trastuzumab plus radiotherapy in patients with HER2-positive, chemotherapy-refractory, locally advanced or locoregionally recurrent breast cancer. Methods and Materials: Eligible patients had measurable disease, normal cardiac function, and biopsy-confirmed residual HER2-positive disease. Patients received weekly trastuzumab (2 mg/kg intravenously), concurrent with radiotherapy (50 Gy) to the breast and regional lymph nodes for 5 weeks. If feasible, surgery followed radiotherapy. The primary endpoint was safety, and the secondary endpoint was efficacy (pathologic responsemore » and interval to symptomatic local progression). Results: Of the 19 patients enrolled, 7 were ineligible and received radiotherapy alone and 12 received therapy per protocol. Of these 12 patients, 11 had a Stage T4 diagnosis. Grade 3 toxicities included skin (n = 2) and lymphopenia (n = 1). One patient experienced delayed wound healing after surgery. No patients developed symptomatic cardiac dysfunction. Of the 7 patients who had undergone mastectomy, 3 (43%) had a substantial pathologic response (complete response or microscopic residual disease), significantly more than a comparison cohort (2 of 38 or 5%, p = .02). The median interval to symptomatic local progression was not reached. The median overall survival was 39 months. Conclusion: This is the first prospective trial providing evidence for a radiosensitizing effect of trastuzumab in breast cancer. The combination of trastuzumab and radiotherapy was well tolerated.« less
  • The study included 135 breast cancer patients (70 patients with locally recurrent breast cancer and 65 patients with locally advanced breast cancer with unfavorable prognostic factors) who received the neutron therapy alone or in combination with the photon therapy. The neutron therapy was shown to be effective in multimodality treatment of patients with locally advanced and locally recurrent breast cancer. The 8-year survival rate in patients without repeated breast cancer recurrence was 87.6 ± 8.7% after the neutron and neutron-photon therapy and 54.3 ± 9.2% after the electron beam therapy.
  • Background and Purpose: Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study ( (www.embracestudy.dk)) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. Methods and Materials: In total, 588 patients with a median follow-up timemore » of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. Results: At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Conclusion: Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal morbidity is still pronounced with currently applied IGABT, and it needs further attention.« less
  • Purpose: This study analyzed functioning and symptom scores for longitudinal quality of life (QoL) from patients with locally advanced cervical cancer who underwent definitive chemoradiation therapy with image guided adaptive brachytherapy in the EMBRACE study. Methods and Materials: In total, 744 patients at a median follow-up of 21 months were included. QoL was prospectively assessed using European Organization for Research and Treatment of Cancer Quality of Life core module 30 (EORTC QLQ-C30) and EORTC cervical cancer module 24 (CX24) questionnaires at baseline, then every 3 months during the first year, every 6 months in the second and third years, and finally yearly thereaftermore » in patients with no evidence of disease. Outcomes were evaluated over time and compared to those from an age-matched female reference population. Results: General QoL and emotional and social functioning were impaired at baseline but improved during the first 6 months after treatment, to reach a level comparable to that of the reference population, whereas cognitive functioning remained impaired. Both social and role functioning showed the lowest scores at baseline but which increased after treatment to reach a plateau at 6 months and then declined slightly at 3 and 4 years. The overall symptom experience was elevated at baseline and decreased to a level within the range of that of the reference population. Similarly, tumor-related symptoms (eg, pain, appetite loss, and constipation), which were present before treatment, decreased substantially at the first follow-up after treatment. Several treatment-related symptoms developed either immediately after and persisted over time (diarrhea, menopausal symptoms, peripheral neuropathy, and sexual functioning problems) or developed gradually after treatment (lymphedema and dyspnea). Conclusions: This longitudinal prospective QoL analysis showed that patients' general QoL and functioning were impaired before treatment compared to those of reference data. Several tumor-related symptoms resolved after treatment, and functioning and general QoL returned to that of the level of the reference population, indicating a transient impact of diagnosis and treatment. However, several treatment-related symptoms and problems did develop and persist, either immediately or gradually after treatment.« less
