A phase II randomised study to evaluate the efficacy of aprepitant plus palonosetron for preventing delayed-phase CINV associated with TC therapy in gynaecological cancer.

AIM: Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequently encountered side effects of cancer treatment. Severe CINV can lead patients to refuse chemotherapy, which ultimately affects cancer outcomes. The development of fairly new antiemetic agents, 5-hydroxytryptamine-3 receptor antagonists, palonosetron and neurokinin-1 receptor antagonists and aprepitant has reduced the risk and incidence of CINV. In this study, we assessed the efficacy of aprepitant plus palonosetron against palonosetron for CINV in patients receiving moderately emetic cancer chemotherapy (paclitaxel and carboplatin combination [TC] therapy). METHODS: Between November 2010 and March 2014, 78 patients with gynecological cancer treated with TC therapy were randomized into two groups: an aprepitant group (administered aprepitant, dexamethasone and palonosetron) and a control group (administered dexamethasone and palonosetron). The primary study endpoint was complete response, defined as the complete absence of emetic events in the delayed phase. RESULTS: The complete response rate in the delayed phase differed significantly between the two groups, with 82% in the aprepitant group and 97% in the control group (P = 0.025). CONCLUSION: The combination of aprepitant and palonosetron appears to be of greater efficacy than palonosetron alone for the prevention of delayed-phase CINV induced by TC therapy.

Long-term efficacy and safety of aromatase inhibitor use for leiomyomatosis peritonealis disseminata.

Leiomyomatosis peritonealis disseminata is a rare disease characterized by pelvic smooth-muscle nodules of various sizes. It is sometimes misdiagnosed as ovarian or peritoneal carcinoma metastasis; therefore, surgical excision for pathological diagnosis is required. Treatment options include bilateral salpingo-oophorectomy (BSO), gonadotrophin-releasing hormone agonist therapy, and aromatase inhibitor therapy. All of these suppress estrogen levels, but a standard treatment has not been established. A 40-year-old woman had multiple pelvic tumors, suspicious for ovarian cancer. She underwent laparotomy, where frozen sections of the nodules revealed leiomyomatosis peritonealis disseminata. After she completed gonadotrophin-releasing hormone agonist therapy, we performed a total abdominal hysterectomy and BSO with residual-nodule resection, but the nodules recurred 6 months after surgery. We then started letrozole, and 3 years have now elapsed without nodule enlargement or development of new lesions. The long-term use of aromatase inhibitor therapy is thought to be effective and safe for patients with recurrence after BSO.

Outcome of Neoadjuvant Intra-Arterial Chemotherapy and Radical Hysterectomy for Treatment of Bulky Stage IB to Stage IIB Uterine Cervical Cancer: Can Postoperative Irradiation Be Avoided?

OBJECTIVES: We evaluated whether our neoadjuvant intra-arterial chemotherapy (NAIC) effectively precludes the need for postoperative radiation therapy in patients treated by radical hysterectomy for IB2 to IIB cervical cancer. MATERIALS AND METHODS: Study subjects were 52 patients with a bulky cervical tumor diagnosed and treated at Juntendo University Hospital or Juntendo Nerima Hospital. The NAIC combined cisplatin, epirubicin, mitomycin-C, and 5-fluorouracil; and radical hysterectomy was to be performed after 2 cycles. The main variables analyzed were clinical and histologic response to NAIC, NAIC-related adverse events, adjuvant chemotherapies, relapse-free and overall survival, recurrence, and prognostic factors. RESULTS: Patients were judged eligible for radical hysterectomy, and 51 underwent the surgery. The overall positive response (complete response [CR] + partial response [PR]) to NAIC was 88.5%. Median follow-up time was 84 months (5-136 months). Three-year relapse-free survival and overall survival were 80.5% and 77.8%, respectively. The recurrence rate was 19.2% (10/52 patients). Seven (13.5%) of the 52 patients died from the disease during follow-up. Lymph node status (positive vs negative) and the histologic effect of NAIC (grades 0-1 vs grades 2-3) were shown to be prognostic factors (P = 0.024 and P = 0.021, respectively). CONCLUSIONS: Our NAIC strategy seems to be well tolerated and beneficial for patients with bulky IB2 to IIB cervical cancer. With this strategy, radiation therapy remains an option in cases of recurrence. For cases in which lymph node metastasis is found or the histologic effect of NAIC is low, our adjuvant chemotherapy regimen may need adjustment to improve prognosis.

Successful pregnancy with stage IB2 uterine cervical cancer: A case report.

BACKGROUND: Although cervical cancer is one of the most common malignancies in pregnancy, its management mainly follows the guidelines for nonpregnant disease state. Within the limited time, patients, and healthcare workers must make difficult decisions to either delay treatment until documented fetal maturity or start immediate treatment based on the disease stage. CASE: The patient was a 37-year-old woman: gravida 1, para 0. Her cervical cytology revealed a high-grade squamous intraepithelial lesion at 8 weeks' gestation. Moreover, invasive squamous cell carcinoma was suspected based on the findings of uterine cervix biopsy. Cervical conization was performed at 11 weeks' gestation, confirming a histopathological diagnosis of squamous cell carcinoma, pT1b2. Cervical cytology findings continued to be negative for intraepithelial lesion or malignancy from 2 weeks after conization until 2 weeks before a cesarean section. In addition, we performed abdominal pelvic lymphadenectomy at 16 weeks' gestation to determine whether the patient could continue her pregnancy. No lymph node metastasis or local recurrence was observed. Finally, a cesarean section and modified radical hysterectomy were performed at 35 weeks' gestation. There was no carcinoma invasion or metastasis. A baby girl weighing 2056 g was delivered with 1- and 5-min Apgar scores of 8 and 9, respectively. Five years postoperatively, there was no evidence of cancer recurrence. CONCLUSION: Management of cervical cancer during pregnancy by using a combination strategy of deep conization and pelvic lymphadenectomy could be an effective strategy for carefully and safely assessing risks of recurrence and metastasis.

CT-Guided Pelvic Lymph Nodal Brachytherapy.

PURPOSE: This is a report of our initial experience using computed tomography (CT)-guided interstitial high dose rate (HDR) brachytherapy to treat bulky pelvic nodal metastases as a part of definitive radiotherapy. MATERIAL AND METHODS: Between February 2015 and April 2019, 14 cervical/endometrial cancer patients presenting with bulky pelvic node(s) underwent nodal interstitial brachytherapy boost in our institution. In total, 17 nodes were treated. The median maximum diameters of the positive nodes at the time of diagnosis and at the first nodal implant were 25 mm (range: 10-65 mm) and 16 mm (range: 9-51 mm), respectively. Dosimetry data of the lymph nodal target volume and small bowel were collected and compared using the paired-sample t-test. Treatment-related toxicities were classified using the Common Terminology Criteria for Adverse Events version 4.0. RESULTS: The median follow-up time for all patients was 26 months. Local recurrence in pelvic nodes occurred in one patient (7%) after 16 months. One patient experienced grade 3 bladder bleeding, and one patient experienced grade 2 pubic bone fracture. No patient had grade 2 or greater gastrointestinal toxicity. In the dosimetric analysis, the mean nodal brachytherapy D90% in terms of the total equivalent dose of 2 Gy (EQD2) was 65.6 Gyαß10. The mean small bowel dose (SBD)0.1cc and SBD1cc in terms of the total EQD2 were 60.4 and 56.5 Gyαß3, respectively. Nodal D90% was significantly higher in terms of the total EQD2 than the SBD0.1cc (p = 0.003) and SBD1cc (p < 0.001). The Kaplan-Meier 2-year pelvic control estimate was 90%. CONCLUSIONS: CT-guided interstitial HDR pelvic nodal brachytherapy appears to be well tolerated with excellent local control in cervical or endometrial cancer patients with bulky pelvic nodes. This approach may offer a useful therapeutic option for unresected bulky pelvic nodes.

Coexistence of Cervical Leiomyosarcoma and Gastric-Type Adenocarcinoma In Situ with Extensive Extension to the Endometrium and Fallopian Tube.

Cervical leiomyosarcoma is known to be rare from the previous reviews of a large number of malignant cervical tumors. The patient was a 66-year-old woman with irregular vaginal bleeding. She underwent modified radical hysterectomy and bilateral salpingooophorectomy. Histopathologically, we diagnosed the coexistence of uterine cervical leiomyosarcoma and cervical gastric-type adenocarcinoma in situ with endometrial lesions that had continuous and skip patterns and fallopian tubal lesions with a partial lesion. To the best of our knowledge, cases of synchronous leiomyosarcoma and cancers have not often been reported; only two cases of synchronous cervical leiomyosarcoma and cervical squamous cell carcinoma have been published. This case is the first presentation of coincidental primary cervical leiomyosarcoma and cervical gastric-type adenocarcinoma in situ. Additionally, we considered cervical gastric-type adenocarcinoma in situ with continuous lesions on the endometrium and skip lesions on the left fallopian tube.

Cystic Endometrioma with Coexisting Fibroma Originating in a Supernumerary Ovary in the Rectovaginal Pouch.

A supernumerary ovary is an exceedingly rare disorder, in which the structure containing ovarian tissue is located at some distance from the normally placed ovary. 16 cases of endometriosis or tumors originating in a supernumerary ovary have been published in the English literature, but no case of coexisting endometriosis and a tumor has been published. We present the case of a 40-year-old female with cystic endometrioma with coexisting fibroma originating in a supernumerary ovary in the rectovaginal pouch. The present case is the first to be reported with coexisting endometriosis and a tumor originating in a supernumerary ovary. Our experience with this case and the results of our previous studies of rectovaginal endometriosis indicated that the possibility of originating in a supernumerary ovary shall be examined in cases of cystic endometrioma in the rectovaginal pouch.
