Pelvic metastatic squamous cell carcinoma of unknown primary site: A case report and brief literature review.

RATIONALE: Cancer with unknown primary site is a kind of disease that is difficult to deal with clinically, accounting for 2% to 9% of all newly diagnosed cancer cases. Here, we report such a case with pelvic metastatic squamous cell carcinoma of an unknown primary site and review the relevant literature. PATIENT CONCERNS DIAGNOSES: A 43-year-old Chinese female patient was referred to our hospital and initially diagnosed as "malignant tumor of right adnexal area?, obstruction of right ureter, secondary hydronephrosis". INTERVENTIONS: Thereafter cytoreductive surgery was performed which included a total hysterectomy, left adnexectomy, partial omentum resection, pelvic lymph node dissection, and para-aortic lymph node dissection. The primary lesion could not be identified by supplementary examination and postoperative pathology. The patient was diagnosed as pelvic metastatic squamous cell carcinoma whose primary site was unknown. To prevent a recurrence, we administered adjuvant chemotherapy for the patient. OUTCOMES: The patient was followed up after treatment, complete remission has been maintained for 72 months, and no recurrence or metastasis has been found. LESSONS: Our case demonstrates that surgery combined with chemotherapy could be helpful for pelvic metastatic squamous cell carcinoma of unknown primary site.

PATL2 regulated the apoptosis of ovarian granulosa cells in patients with PCOS.

AIM: PCOS often showed abnormal follicular development. Previous studies have found that the increased apoptosis of granulosa cells (GCs) is one of the key factors leading to follicular dysplasia. It has been found that the decrease or deletion of PATL2 function can significantly inhibit the development and maturation of human oocytes. We found that PATL2 was also expressed in human ovarian GCs, suggesting that PATL2 may be involved in the regulation of related biological events in GCs. This study aims to explore the function of PATL2 on regulation of GCs apoptosis, and the potential role of PATL2 in the development of PCOS-related abnormal follicles. MATERIALS AND METHODS: The follicular GCs of PCOS patients and normal ovulating female patients were collected. Moreover, human granular cell line (KGN) was used for in vitro experiments. RESULTS: (1) The maturation rate and fertilization rate of oocytes in the PCOS group were significantly lower than those in the normal control group (p＜0.05). (2) Flow cytometry and TUNEL staining showed that the apoptosis level of GCs in the PCOS group was significantly increased. (3) Immunofluorescence and Western Blot showed that the PATL2 expression level of GCs in the PCOS group was significantly reduced. (4) Knocking down the expression of PATL2 by siRNA significantly prevented the apoptosis of GCs. CONCLUSIONS: Reduced PATL2 could resulted in the increased apoptosis level of ovarian GCs, which might be closely related to the occurrence and development of abnormal follicles in PCOS.

[Expert consensus statement on Kangfu Xiaoyan Suppository in treatment of pelvic inflammatory in clinical practice].

Kangfu Xiaoyan Suppository is widely used in the treatment of gynecological inflammatory diseases. Long-term clinical application and a certain amount of research evidences show that Kangfu Xiaoyan Suppository can alleviate the clinical symptoms of pelvic inflammatory diseases,reduce the recurrence rate,and relieve sequelae,with a better safety and economic characteristics. As a type of nationally protected traditional Chinese medicine and type B medicine included in medical insurance,it has been selected as a Chinese patent medicine for rectal administration. It was included in the Guidelines for diagnosis and treatment of common gynecological diseases of traditional Chinese medicine published by the Chinese Academy of Traditional Chinese Medicine in 2012,the Pelvic inflammatory diseases diagnosis and treatment guidelines issued by the Infectious Diseases Collaborative Group of the Obstetrics and Gynecology Branch of the Chinese Medical Association in 2014,and the group standard of Single use of traditional Chinese medicine/combined antibiot guidelines for clinical practice-pelvic inflammatory diseases of the Chinese Academy of Traditional Chinese Medicine in 2017. To further enhance clinicians' understanding of the drug and better guide its rational clinical use,experts from the field of gynecology of traditional Chinese and Western medicine were invited to develop and compile this expert consensus. This consensus takes full account of clinical evidences and expert clinical experience,and form recommendations for clinical problems based on evidences and consensus recommendations for clinical problems without evidence by nominal grouping method. The expert consensus is mainly formed in the consideration of six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on clinical research evidences and expert experience,this consensus provides a preliminary reference for the clinical use of the drug in a concise and clear format. However,evidence-based support is still required in a large number of high-quality studies,and this consensus will be revised in the future according to new clinical problems and the update of evidence-based evidence in practical application.

[Concurrent chemoradiotherapy versus radiotherapy in advanced cervical carcinoma].

BACKGROUND & OBJECTIVE: Cisplatin-based concurrent chemoradiotherapy has become the standard treatment modality for locally advanced cervical cancer. However, the optimal chemotherapy regimen combined with radiotherapy remains controversial. This study was to compare the therapeutic efficacy and toxicity of concurrent chemoradiotherapy with those of radiotherapy, and those among different regimens of concurrent chemoradiotherapy for stage IIB-IIIB cervical cancer. METHODS: From Jan. 2003 to Dec. 2004, 285 patients with stage IIB-IIIB cervical cancer treated in Maternal and Child Health Hospital of Jiangxi Province were randomly assigned to receive radiotherapy alone or concurrent chemoradiotherapy. According to different chemotherapy regimens, patients in the concurrent chemoradiotheapy group were randomly chosen to receive radiotherapy with chemotherapy of bleomycin and cisplatin (RT+BP), radiotherapy with chemotherapy of taxol and carboplatin (RT+TP), and radiotherapy with chemotherapy of 5-fluorouracil and cisplatin (RT+FP). The 3-year survival rates and toxicity of different groups were compared. RESULTS: After a median follow-up of 42 months, the 3-year survival was higher in the concurrent chemoradiotheray group (75%) than in the radiotherapy group (65%) (P=0.042). Acute treatment-related toxicity (grade III and IV) was higher in the concurrent chemoradiotherapy group than in the radiotherapy group (P<0.001); while the delayed treatment-related toxicity was similar in the two groups (P=0.613). The 3-year survival rates of BP, TP and FP chemoradiotherapy groups were 74%, 80% and 71%, without significant differences (P=0.792). Acute toxicities (grade III and IV) and delayed toxicities were similar among the three groups. CONCLUSIONS: Concurrent chemoradiotherapy significantly improves the survival for patients with stage IIB-IIIB cervical cancer compared to radiotherapy alone. Among the three chemoradiotherapy regimens, radiotherapy combined with taxol and carboplatin exerts a slightly higher 3-year survival than the other two regimens with tolerable toxicity.

[Clinical analysis of 48 patients with vaginal enlarged amputation of cervix].

OBJECTIVE: To evaluate the feasibility and safety of vaginal enlarged amputation of cervix to treat patients with cervical cancer of stage Ia1 and cervical intraepithelial neoplasia grade III (CIN III) who were unfit for conization surgery. METHODS: From July 2002 to May 2007, patients with cervical cancer at stage Ia1, diagnosed by pathology after loop electrosurgical excision procedure (LEEP), large area CIN III (the area of lesion>or=3/4 on colposcopy), CIN III coexisted with vaginal intraepithelial neoplasia (VAIN) in the superior segment of vagina, CIN II-III recurrence or with residual lesion, positive margin after conization of cervix, who wanted to preserve fertility and (or) corpus uteri were selected to receive vaginal enlarged amputation of cervix. RESULTS: Forty-eight cases including 5 with cervical cancer in stage Ia1, 38 with large area CIN III (9 with gland involvement), 2 with residual lesion and 2 with positive margin after LEEP, 1 recurrence after cold knife conization, received the procedure successfully. The median age was 34 years (range 27-40), median operation time was 60 minutes (range 30-100), median blood loss was 40 ml (range 5-300), and median hospital stay was 10 days (range 7-17). After follow-up 1-39 months, no patient had postoperative complications and recurrence, and all patients resumed normal menstrual cycle and sexual life. CONCLUSION: Vaginal enlarged amputation of cervix appears to be a safe and feasible procedure for patients with cervical cancer at stage Ia1 and CIN III who are unfit for conization surgery.
