BACKGROUND In response to findings that pelvic lymphadenectomy does not have any therapeutic benefit for endometrial cancer, we aimed to establish whether complete, systematic lymphadenectomy, including the para-aortic lymph nodes, should be part of surgical therapy for patients at intermediate and high risk of recurrence. METHODS We selected 671 patients(More)
OBJECTIVE The aim of this study was to determine the incidence rate of lower-extremity lymphedema after systematic lymphadenectomy in patients with uterine corpus malignancies and to elucidate risk factors for this type of lymphedema. METHODS A retrospective chart review was carried out for all patients with uterine corpus malignant tumor managed at(More)
Lower-limb lymphedema (LLL) is a prevalent complication that is encountered after treatment for gynecological malignancies. The aim of this study was to evaluate the risk factors for postoperative LLL in patients with cervical cancer. We conducted a retrospective chart review for patients who had undergone surgery, including systematic lymphadenectomy, for(More)
Growing teratoma syndrome (GTS) is defined as enlarging masses during or after chemotherapy for germ cell tumors, and containing only mature teratoma components. A surgical resection is important to confirm a diagnosis and thereby result in the resection of the most appropriate therapeutic management. GTS is a rare event in association with ovarian germ(More)
OBJECTIVE The objective of this study was to compare the initial failure sites in patients with endometrial cancer who underwent surgical treatment including pelvic lymphadenectomy with or without para-aortic lymphadenectomy. METHODS A retrospective chart review was carried out for 657 endometrial cancer patients with no residual disease after initial(More)
OBJECTIVE Concurrent chemoradiotherapy (CCRT) is the primary treatment for locally advanced cervical cancer. We studied prognostic factors for patients treated with CCRT. METHODS We retrospectively reviewed records of 85 consecutive patients with cervical cancer who were treated with CCRT between 2002 and 2011, with external beam radiation therapy,(More)
OBJECTIVE The aim of this study was to clarify the clinical significance of isolated tumor cells (ITCs) or micrometastasis (MM) in regional lymph nodes in patients with International Federation of Gynecology and Obstetrics (FIGO) stage I to II endometrial cancer. METHODS In this study, a series of 63 patients with FIGO stage I to II were included, who had(More)
OBJECTIVE The aim of this study was to determine the rate of occult metastasis, including isolated tumor cells, in para-aortic lymph nodes of patients with stage IIIC1 endometrial cancer who underwent pelvic and para-aortic lymphadenectomy. METHODS A series of 15 patients who had undergone combined pelvic and para-aortic lymphadenectomy during the period(More)
A cervical polyp complicated by severe hemorrhage was removed from a 43-year-old Japanese woman (gravida 0), who had undergone tubectomy on the right side 10 years previously. The polyp was diagnosed by immunohistochemical studies as placental site trophoblastic tumor of the cervix, but no metastatic foci were found in any other uterine site. The tumor was(More)
