Abstract Background. To control advanced cervical squamous cell carcinoma more effectively and more easily, we used neoadjuvant chemotherapy, with three drugs carboplatin, ifosfamide, and peplomycin (PIP), in a study performed from July 1990 to October 1994 in nine Institutions. Methods. Sixty-five patients with untreated, inoperable squamous cell carcinoma of the cervix were treated with carboplatin (300 mg/m2 IV; low-dose PIP regimen, or 400 mg/m2 IV; high-dose PIP regimen) on day 1, ifosfamide (1000 mg/m2, IV) on days 1–3, and peplomycin (5 mg/body, IM) on days 1–6. The low-dose PIP was given between July 1990 and April 1992, and the high-dose PIP from May 1992 to October 1994. Results. Response rates for the low- and high-dose PIP regimens were 42.9% (12/28) and 59.5% (22/37), respectively. Measurable lesions were recognized in the cervix, pelvic lymph node (PeN), paraaortic lymph node (PAN), lung, and supraclavicular lymph node. Response rates in these individual lesions to our low- and high-dose PIP regimens were 35.7% (10/28) and 55.6% (20/36), respectively in the cervical lesion and more than 50% for both regimens in the PeN and PAN metastatic lesions, while the supraclavicular lymph node metastatic lesions responded poorly to both regimens. After low-dose PIP, surgery was performed in 2 patients (2/28; 7.1%), while after high-dose PIP, 12 patients (12/37; 32.4%) underwent surgery. The 3-year survival rate of patients with high-dose PIP was significantly higher than that of those with low-dose PIP (P 〈 0.01). Conclusions. Neoadjuvant chemotherapy with PIP appears feasible and effective. The link between dosage and treatment response and achievable surgery rate and survival rates suggests that results might be further optimized by considering patients' renal function, and utilizing the Calvert formula for dosing analysis.
