Tailoring adjuvant radiotherapy for stage IB-IIA node negative cervical carcinoma after radical hysterectomy and pelvic lymph node dissection using the GOG score.

OBJECTIVE: The use of adjuvant radiotherapy for early stage node negative patients varies for different institutions. The recognized factors such as deep stromal invasion, lymph vascular space invasion, and size of tumor are the most common factors cited for adjuvant radiotherapy. Studies done have shown that this increases local control but may increase chronic toxicity rates. We report on our use of the GOG score to tailor our treatment decisions. METHODS: A review of all patients staged IB-IIA who underwent Type 3 Radical Hysterectomy and pelvic lymph node dissection (RH) from 1997 to 2007. The GOG score proposed by Delgado et al. was applied, and patients were stratified into 3 groups; <40: no adjuvant treatment, 40-120: Small Field RT (SmRT), and >120: Standard Field RT (StRT) RESULTS: A total of 126 patients matched these criteria. Sixty one patients underwent either SmRT or StRT. There were only 2 known relapses and one death due to inter current illness. The median follow up was 57 months and the 5 year Disease Free Survival was 98.2%. There were no documented Grade 3 or 4 chronic toxicities. There were significantly less (p=0.025) patients with lower limb lymphedema in the SmRT group compared to StRT. CONCLUSION: Our study confirms the utility of the GOG score to tailor radiotherapy for this cohort of patients. This has been proven to be high in efficacy and low in morbidity.

Nonmyeloablative allogeneic stem cell transplantation for nasopharyngeal carcinoma.

We present a case of a patient with metastatic nasopharyngeal carcinoma who failed two lines of palliative combination chemotherapy and was treated with allogeneic nonmyeloablative stem cell transplantation (NST). This patient achieved a durable tumor response, dramatic relief of his symptoms, and elimination of tumor in his bone marrow-an effect likely achieved via a graft-versus-tumor response. Although NST has been explored previously in solid tumors, such as renal cell carcinoma and breast cancer, it has not been widely explored in nasopharyngeal carcinoma. We also present data from a flow cytometric immune analysis and cytokine enzyme-linked immunosorbent assay analysis in the pre- and post-NST period.
