Abstract. Paclitaxel/carboplatin chemotherapy for cancer (TC therapy) exhibits neurotoxicity and causes peripheral neuropathy at a high frequency, which is difficult to cope with. In this study, we investigated the efficacy of Goshajinkigan, a traditional Japanese herbal medicine, for TC therapy-induced peripheral neuropathy. The subjects included in our study were patients with ovarian or endometrial cancer who underwent TC therapy and developed peripheral neuropathy. The patients were randomly divided into Group A, comprising of 14 patients (vitamin B12 treatment), and Group B, comprising of 15 patients (vitamin B12 + Goshajinkigan treatment). The observation period was 6 weeks following treatment initiation, and the evaluation items were as follows: i) the current perception threshold (CPT value) of the peripheral nerve, ii) visual analogue scale for numbness, iii) National Cancer Institute Common Terminology Criteria for Adverse Events v3.0 grade of neurotoxicity, and iv) a questionnaire on the subjective symptoms of peripheral neuropathy (functional assessment of cancer therapy-taxane). These were compared between the groups and no significant differences were noted in any item. However, CTCAE grade 3 neurotoxicity developed in 2 patients (14.3%) after 6 weeks of administration in Group A, whereas no neurotoxicity was observed in Group B. When the change in the frequency of abnormal CPT ratio at 6 weeks of administration from that before treatment was compared between the groups, the frequency of abnormal value was significantly lower in Group B than in Group A (p<0.05). This suggests that Goshajinkigan inhibits the progression of peripheral neuropathy.

We report the clinical profiles and immunohistochemical features of small-cell carcinoma of the uterine cervix. Eleven cases that we have encountered at the Department of Gynecology, Kitasato University Hospital, between 1971 and 2003 are presented. Of 1370 invasive carcinomas of the uterine cervix, the incidence of small-cell carcinoma was 0.8%. Patient ages ranged between 32 and 65 years, with a mean age of 46.3 years. The clinical stages at diagnosis were Ib in four patients, IIb in three, IIIb in three, and IVb in one. All patients presented with abnormal vaginal bleeding. Two patients who are alive with no evidence of disease for 12 years and 3 years 6 months, while eight patients died of primary carcinoma between 4 and 25 months after treatment. Histopathologic findings showed solid nests with marked peripheral palisading pattern and rosette formation. Small tumor cells with scant cytoplasm demonstrated a very high nuclear/cytoplasm ratio and indistinct cell borders. The nuclei were round to oval and demonstrated increased but fine granular chromatin. Nucleoli were indistinct in all cases. Immunohistochemical findings were positive in 81.8% each for neuron-specific enolase and protein gene product 9.5, 72.7% for synaptophysin, 63.6% for chromogranin A, and 54.5% for neural cell adhesion molecule. All specimens were positive for at least one of the above. In conclusion, small-cell carcinoma of the uterine cervix revealed poor prognosis. Making an accurate diagnosis of small-cell carcinoma before performing treatment is of great significance but often difficult. Immunohistochemical analysis using several kinds of neuroendocrine markers is helpful in establishing the correct diagnosis in addition to focusing on characteristic histo- and cytopathologic features

BACKGROUND: The authors evaluated the applicability and usefulness of immunocytochemical staining for cyclin A, p53, estrogen receptor α (ER‐α), and progesterone receptor B (PR‐B) as a preoperative prognostic indicators for endometrial carcinoma using endometrial cytology with the liquid‐based cytology (LBC) method. METHODS: Cytologic specimens from 44 patients who had endometrial carcinoma were prepared with the LBC method. The results of immunocytochemical and immunohistochemical staining for cyclin A, p53, ER‐α, and PR‐B were compared with clinicopathologic parameters and prognosis. RESULTS: Patients who had positive results for cyclin A and p53 and negative results for ER‐α and PR‐B appeared to have unfavorable clinicopathologic characteristics, such as high‐grade histology, advanced clinical stage, lymphovascular space involvement (LVSI), and deeper myometrial invasion (MI), and had a poor prognosis. In contrast, patients who had positive results for ER‐α and PR‐B, and negative results for cyclin A and p53 had favorable characteristics, such well differentiated tumor, early clinical stage, negative LVSI, and less MI, and had a good prognosis. Immunostaining results from cytologic specimens obtained in the clinic and at surgery and from histologic specimens obtained at surgery were correlated positively. CONCLUSIONS: Consistent specimens that were prepared using the LBC method facilitated multiple immunocytochemical analyses. Endometrial cytology with the LBC method was useful for predicting the prognosis of patients with endometrial carcinoma before therapy.
