Tumor cell contamination of peripheral-blood progenitor cells was frequently noted by transcriptase polymerase chain reaction in patients with ovarian cancer. The biological and clinical significance of this finding remains to be elucidated.
The purpose of this study was to determine the efficacy of paclitaxel in combination with cisplatin and granulocyte-colony stimulating factor (G-CSF) for mobilization of peripheral blood progenitor cells (PBPC). Twenty-seven patients with gynecological cancer received paclitaxel and cisplatin (TP, n = 9) or other platinum-based chemotherapy (n = 18) (etoposide and cisplatin [n = 5]; cyclophosphamide, adriamycin, and cisplatin [n = 8]; or pepleomycin, etoposide, and cysplatin [n = 5]). Each combination was followed by G-CSF. The mean number of colony-forming unit granulocyte macrophage (CFU-GM)/kg and CD34+ cells/kg collected per cycle was 1.2 x 105 and 0.8 x 106 after the TP regimen, compared with 2.6 x 105 (P < 0.05) and 2.0 x 106 for patients who received other platinum-based chemotherapy. The CFU-GM target yield (>/=1.0 x 105/kg) was achieved in 56% and 83% patients in the TP and comparison group, respectively. With the TP regimen, a younger age (=50 years of age) and fewer prior chemotherapy cycles (=2) were associated with the CFU-GM targeted yield (<0.05). In conclusion, TP mobilized PBPC less effectively than other platinum-based chemotherapy. Therefore, the TP regimen may need to be changed to another appropriate regimen when PBPC mobilization is planned for high-dose chemotherapy in gynecological cancer patients.
Palmar fasciitis and polyarthritis (PFPA) is an uncommon syndrome characterized by progressive and extensive rheumatic disease. We present the first example of PFPA in association with squamous cell carcinoma of the uterine cervix and peritoneal carcinoma. A 54-year-old woman developed pain in both shoulders and flexion deformities of all fingers in both hands due to an increasing swelling of both palms. She underwent surgery and histologic examination of the removed uterus revealed squamous cell carcinoma, nonkeratinizing type with a small portion of undifferentiated carcinoma. Chemotherapy resulted in an excellent response, during which the arthritic symptoms improved gradually. PFPA can occur in a wide range of cancers and warrants extensive investigation for a malignant tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
