[Efficacy of postoperative simple chemotherapy and concurrent chemoradiotherapy in FIGO stage IB2-IIB cervical cancer].

OBJECTIVE: To evaluate the effectiveness of neoadjuvant chemotherapy (NAC) followed by radical hysterectomy plus postoperative chemotherapy but no radiotherapy for stage IB2-IIB cervical cancer. METHODS: Seventy-nine patients with stage IB2-IIB cervical cancer were treated with NAC followed by radical hysterectomy. According to different adjuvant therapies, patients were divided into postoperative chemotherapy group (47 cases) and postoperative radiotherapy/concurrent chemoradiotherapy group (32 cases). Regimens for NAC and postoperative chemotherapy were BIP (bleomycin+ ifosfamide+ cisplatin/carboplatin) or TP (paclitaxel+ cisplatin/carboplatin). An average of 1.1±0.3 cycles of NAC and 3.4±1.2 cycles of postoperative chemotherapy were prescribed. RESULTS: Toxicities due to chemotherapy were generally tolerable. Overall response rate of NAC was 88.6%. With a median follow-up period of 42 months, the three-year progression-free survival rates of the two groups were 88.5% and 84.3%, the total survival rates were 90.3% and 86.4%, respectively. There was no statistically significant difference. The recurrent rates were 10.6% and 21.8% in the two groups. In the absence of radiotherapy, pelvic recurrence was observed in two patients; the other three had distant metastases. CONCLUSION: The results indicate that NAC followed by surgery plus postoperative chemotherapy but no radiotherapy offers a viable option in the treatment of stage IB2-IIB cervical cancer. The patients can tolerate the side effects of chemotherapy with better efficacy.

Clinical features of IgA nephropathy with serum ANCA positivity: a retrospective case-control study.

BACKGROUND: The coexistence of IgA nephropathy (IgAN) and antineutrophil cytoplasmic autoantibodies (ANCAs) is relatively rare. Only a few studies have reported the features of these patients. METHODS: We studied the clinical and histological features of 20 ANCA-positive IgAN patients. They were compared with ANCA-negative IgAN patients (n = 40) and ANCA-associated systemic vasculitis (AASV) patients (n = 40) with a randomly selected and matched proportion of crescentic glomeruli. Furthermore, 9 ANCA-positive crescentic IgAN patients out of the 20 cases were compared with two control groups with crescentic nephritis. RESULTS: ANCA-positive IgAN patients showed older age, lower haemoglobin and higher inflammatory indicator levels at baseline, and a higher percentage of general symptoms and pulmonary involvement, compared with ANCA-negative IgAN patients, and were comparable to AASV patients. Histologically, there was a significantly higher percentage of fibrinoid necrosis in glomeruli in ANCA-positive IgAN patients and in AASV patients compared with ANCA-negative IgAN patients (35, 25 and 0%, respectively, P = 0.003). After immunosuppressive therapy, ANCA-positive crescentic IgAN patients were more likely to withdraw from dialysis (75 versus 9.1%, P = 0.03) and not to reach end-stage renal disease within 6 months (11.1 versus 66.7%, P = 0.01) compared with ANCA-negative crescentic IgAN patients. CONCLUSIONS: IgAN patients with ANCA positivity showed more severe clinical and histological features when compared with ANCA-negative IgAN patients and were comparable to AASV patients. However, renal prognosis was relatively better in ANCA-positive crescentic IgAN patients after aggressive immunosuppressive therapy in the short term, compared with ANCA-negative patients.
