PABCREATIC neuroendocrine tumours are uncommon neoplasms of the pancreas. They may cause a clinical syndrome due to hormone overproduction. Glucagonoma is a rare kind of pancreatic tumors. Here we report a case of glucagonoma. Hypercalcemia occurred when the patient underwent octreotide acetate long-acting release.

Endometrial hyperplasia (EH) comprises a spectrum of changes in the endometrium ranging from a slightly disordered pattern that exaggerates the alterations seen in the late proliferative phase of the menstrual cycle to irregular, hyperchromatic lesions that are similar to endometrioid adenocarcinoma. Generally, EH is caused by continuous exposure of estrogen unopposed by progesterone, polycystic ovary syndrome, tamoxifen, or hormone replacement therapy. Since it can progress, or often occur coincidentally with endometrial carcinoma, EH is of clinical importance, and the reversion of hyperplasia to normal endometrium represents the key conservative treatment for prevention of the development of adenocarcinoma. Presently, cyclic progestin or hysterectomy constitutes the major treatment option for EH without or with atypia, respectively. However, clinical trials of hormonal therapies and definitive standard treatments remain to be established for the management of EH. Moreover, therapeutic options for EH patients who wish to preserve fertility are challenging and require nonsurgical management. Therefore, future studies should focus on evaluation of new treatment strategies and novel compounds that could simultaneously target pathways involved in the pathogenesis of estradiol-induced EH. Novel therapeutic agents precisely targeting the inhibition of estrogen receptor, growth factor receptors, and signal transduction pathways are likely to constitute an optimal approach for treatment of EH.

BACKGROUNDThere is an association between postmenopausal tamoxifen therapy and endometrial pathologies. We investigated the usefulness of diagnostic hysteroscopy and transvaginal ultrasonography (TVS) and estimated whether diagnostic hysteroscopy improves detection of endometrial pathologies in postmenopausal breast cancer patients on tamoxifen.

METHODSNinety-seven postmenopausal breast cancer patients who had been taking tamoxifen 20 mg/d for ≥ 6 months went through TVS, diagnostic hysteroscopy, and endometrial biopsy examinations. The presence of endometrial histopathologic features with abnormal TVS and diagnostic hysteroscopic findings were correlated.

RESULTSNo endometrial cancer was found in any of the 97 patients. Fifty-three patients (54.6%) developed endometrial polyps as diagnosed histopathologically. Fifty-nine patients (60.8%) tested positive in TVS exams, of whom 43 had polyps, four had hyperplasia, and 12 atrophy. Thirty-eight patients (39.2%) tested negative in TVS exams, of whom 10 had polyps, three hyperplasia, and 25 atrophy. TVS exams presented 63.6% specificity, 81.8% sensitivity, 72.9% positive-predictive value, and 73.7% negative-predictive value, whereas the corresponding values of diagnostic hysteroscopy were 100%, 98.1%, 100%, and 97.8% respectively. The correct ratio of hysteroscopy was significantly higher than that of TVS (P = 0.000).

CONCLUSIONSIn postmenopausal breast cancer patients treated with tamoxifen, TVS alone is not sufficient for the detection of endometrial pathologies. Additional use of diagnostic hysteroscopy considerably improves the detection of polyps, thus significantly reducing the rate of false-negative findings of endometrial pathologies.

PURPOSE: Granulomas resulting from the administration of luteinizing hormone-releasing hormone analogues (LH-RH analogues) are thought to be very rare. We report on our clinical experience with injection-site granulomas that result from the administration of LH-RH analogues, and we evaluate the incidence rate of these granulomas. MATERIALS AND METHODS: We used the clinical records of 118 patients who were administered LH-RH analogues in 2005. We describe the clinical data of patients who experienced injection-site granulomas and evaluated the incidence rate. RESULTS: Five patients demonstrated injection-site granulomas due to LH-RH analogue administration. The incidence rate was 4.2% (5 of 118 patients). Most of the granulomas occurred after the first or second administration of 11.25mg of leuprorelin acetate. CONCLUSION: The occurrence of granulomas resulting from the administration of LH-RH analogues was thought to be very rare. Our study, however, revealed a higher incidence rate than expected, especially for leuprorelin acetate.

The increased survival of patients with breast cancer has given rise to other problems associated with the complications of chemotherapy. One major complication is premature ovarian failure, an especially harmful outcome for women of reproductive age. This study was performed to evaluate the efficacy of GnRH agonist (GnRHa) treatment on protecting ovarian function in young breast cancer patients (30.59+/-5.1 yr) receiving chemotherapy after surgery. Twenty-two women were enrolled and given subcutaneous injections of leuprolide acetate (3.75 mg) every 4 weeks during chemotherapy. Follow-up laboratory tests (luteinizing hormone [LH], follicle stimulating hormone [FSH], and estradiol) were performed 1, 3, and 6 months after chemotherapy. Menstruation patterns and clinical symptoms were followed up for a mean duration of 35.6+/-1.7 months. FSH and LH levels were normal in all patients 6 months after completing chemotherapy (8.0+/-5.3, 4.4+/-2.7 mIU/mL, respectively). During follow-up, none of the patients complained of menopausal symptoms and 81.8% experienced recovery of menstruation. This report is the first trial of GnRHa as a treatment modality to protect ovarian function during adjuvant chemotherapy in young Korean breast cancer patients.

PURPOSE: The short-term safety and efficacy of zoledronic acid for the treatment of skeletal metastasis was evaluated in patients with hormone-refractory prostate cancer. PATIENTS AND METHODS: A total of 19 hormone-refractory prostate cancer patients with bone metastases were enrolled. All patients received up to six infusions of zoledronic acid (4mg, given intravenously over 15 minutes, every 3-4 weeks). Safety was assessed by monitoring a`dverse events and serum creatinine levels. Efficacy was assessed by monitoring skeletal-related events, brief pain inventory score, quality of life score, type of pain medication, and analgesic score. Mean age of patients was 67.3 years (46-86 years), mean time from diagnosis of bone metastases was 27.6 months (0-117 months), and mean time from diagnosis of hormone-refractory disease was 7.5 months (0-26 months). RESULTS: There was no clinically significant change in serum creatinine levels. Eleven adverse events (musculoskeletal disorders and systemic disorders) in 8 patients were classed as having a possible relationship to study drug. Fifteen patients completed six courses of zoledronic acid infusion. There were no significant changes in the brief pain inventory composite scores, quality of life questionnaire scores or analgesic score. No new skeletal-related events developed during the treatment period. CONCLUSION: Zoledronic acid administered in this study as a 15-minute infusion demonstrated an acceptable and well-known safety profile in patients with refractory prostate cancer with bone metastases. However, prospective placebo- controlled clinical trials are required to elucidate the efficacy of zoledronic acid.

Breast cancer is the most common type of female cancer. Tamoxifen, a selective estrogen receptor modulator, is widely used to decrease breast cancer recurrence and mortality among patients. However, it also increases the risk of endometrial cancer. This study aimed to assess knowledge and decisional conflict regarding tamoxifen use. Between June and October 2014, breast cancer patients using tamoxifen were consecutively screened and requested to complete a survey including the EQ-5D, Satisfaction with Decision Scale (SWD), Decisional Conflict Scale (DCS), and a self-developed, 15-item questionnaire measuring tamoxifen-related knowledge. The study sample comprised 299 patients. The mean total knowledge score was 63.4 of a possible 100.0 (range, 13.3-93.3). While 73.9% of the participants knew that tamoxifen reduces the risk of breast cancer recurrence, only 57.9% knew that the drug increases endometrial cancer risk. A higher education level (> or =college) was associated with a higher, total knowledge score (beta = 4.291; P = 0.017). A higher knowledge score was associated with a decreased DCS score (beta = -0.366; P < 0.001). A higher SWD score was also associated with decreased decisional conflict (beta = -0.178; P < 0.001). In conclusion, the breast cancer patients with higher levels of tamoxifen-related knowledge showed lower levels of decisional conflict regarding tamoxifen use. Clinicians should provide the exact information about tamoxifen treatment to patients, based on knowledge assessment results, so as to aid patients' decision-making with minimal conflict.

AIMTo study the effect of combined androgen block therapy on hemoglobin and hematocrit values in patients with prostate cancer.

METHODSOne hundred and thirty-six patients with adenocarcinoma of prostate were treated with combined androgen block (orchiectomy and flutamide 250 mg, tid). Complete blood counts were determined before and after 1, 2, 3, 6, 9 and 12 months of therapy.

RESULTSThe hemoglobin and hematocrit levels declined significantly in all patients and at all the time points after treatment (P<0.05).

CONCLUSIONProstate cancer patients treated with combined androgen block would develop obvious anemia. Recombinant human erythropoietin can be used to treat patients with severe anemia.
