The aim of this study was to investigate whether systematic lymphadenectomy is necessary in suboptimally cytoreduced patients with stage III ovarian carcinoma. ⋯ Lymphadenectomy seems not to have an evident prognostic value and a benefit on survival in suboptimally debulked patients with stage III ovarian carcinoma.

Dihydropyrimidine dehydrogenase (DPD) activity in tumor cells has been suggested to be one of the factors determining the effectiveness of 5-fluorouracil (5-FU). In the present study, we analyzed DPD expression in tumors and investigated retrospectively the relationship between the efficacy of UFT (Tegafur + Uracil) as adjuvant chemotherapy and DPD expression in nonsmall-cell lung cancer (NSCLC). ⋯ DPD expression may predict the efficacy of UFT after surgery for p-stage I NSCLC. A prospective study is needed to confirm the role of DPD expression as a predictor of UFT efficacy.

Comparative Study
Postoperative morbidity, mortality, and survival in lung cancer associated with idiopathic pulmonary fibrosis.
Although postoperative morbidity and mortality rates in patients with lung cancer have decreased with advances in perioperative management, those patients with idiopathic pulmonary fibrosis (IPF) remain at a high risk of complication and death. The frequency of postoperative morbidity and mortality rates in patients with lung cancer who have IPF have seldom been reported, however. ⋯ Patients with IPF showed markedly higher postoperative pulmonary morbidity and mortality than those without IPF. The survival rate of patients with IPF was lower because of pulmonary complications. Careful preoperative evaluation and perioperative management are required to achieve optimal surgical outcome in patients with lung cancer who have IPF.

After resection, desmoid tumors are associated with a recurrence rate that is typically 25-50%. Although this is an unusual problem, we instituted a prospective cohort study with neoadjuvant chemotherapy and radiation, followed by surgical resection, in an effort to improve local control. ⋯ For potentially resectable lesions, this protocol provides excellent local control, even in those with recurrent disease. Neoadjuvant treatment with doxorubicin and radiotherapy appears to be a better option than surgery alone, or surgery and adjuvant radiotherapy. These results need to be confirmed in larger, prospective randomized trials.

Neoadjuvant chemotherapy in locally advanced breast cancers produces histologically evaluable changes and frequently reduces the size of the primary tumor. Local clinical response to neoadjuvant chemotherapy may correlate with response of distant metastases. Therefore, clinical or pathological factors, which predict or assess response to treatment, may predict outcome after consideration for initial extent of disease. ⋯ This study of patients treated with neoadjuvant chemotherapy for locally advanced breast cancers found little evidence that measurable clinical or pathologic changes attributable to chemotherapy predicted survival. Axillary lymph node status, associated with young age, was the most important prognostic indicator in these patients.
