Methods One hundred and forty-five patients with cervical squamous cancer stagesⅠb-Ⅱa were investigated, among which17 patients with bulky tumors (≥4 cm) were managed by cisplatin-based chemotherapy for 1-2 courses followed by radical hysterectomy and pelvic lymphadenectomy (BC group). The change of tumor size, pelvic lymph nodes metastasis, cervical wall invasion, the involvement of surgical specimen margin, and the blood loss during operation were assessed after opera-tion and compared with those in 51 patients with bulky tumors (BN group) and 77 patients with small local tumors (S group) who underwent surgery directly. Results (1) The tumor size of 17 patients in BC group were decreased in various degrees after chemotherapy, with 13 pati-ents of clinical effectiveness (76.47%). And the responsiveness pertained to neither histological differentiation nor size of local tumors. (2) Post-operative histology has showed that patients in BC and BN group have higher incidence of lymph node metastasis and deep cervical infiltration (5/68 and 3/68, respectively) than in S group (1/77 and 1/77, respectively) while with no statistical significance. (3) Blood loss during operation in BC group was less than BN and S group. (4) Seventeen patients, including those underwent surgeries of vaginal prolongation and/or ovarian transposition, appeared disease-free survival within the follow-up time. Conclusions Most of patients with bulky early stage cervical squamous carcinoma are sensitive to cisplatin-based chem-otherapy, which could greatly reduce local tumor size and in turn facilitate the following operation by well controlling blood loss.展开更多

Methods： Forty-two cases with cervical cancer （FIGO lib to IVa） were divided randomly into two groups, radiotherapy alone （RT group： 21 cases） and radiation combines chemotherapy （nedaplatin and megestrol） （RT ＋ C group： 21 cases）. There was no difference of radiotherapy between the two groups, the RT ＋ C group accepted nedaplatin injection during the radiation weekly, according to 30 mg/m^2 ,these regimen were given for 4-5 weeks. This group was received an oral medicine megestro1160 mg every day during the treatment. Results： The RT ＋ C group： the complete remission rate was 80.9% （17/21）, the partial remission rate was 19.1% （4/21）, the effective rate was 100%. The RT group： the complete remission rate was 38.1% （8/21） and partial remission rate was 32.9% （9/21）, the effective rate was 81.0%. The total effective rate and complete remission rate of RT ＋ C group were higher than RT group. There was significant difference between the two groups. The 1-year survival rates respectively were 100% （21/21） in RT ＋ C group, 80.9% （17/21） in RT group. There was statistically significant difference between the two groups （x^2 = 4.42 〉 3.84, P 〈 0.05）. Conclusion： The nedaplatin and megestrol combine chemoradiotherapy can improve the early outcome of the advanced cervical cancer, and the adverse effects was raised, but that can be endured.展开更多

Methods： The fresh carcinoma tissues were collected from 10 untreated cervical cancer patients and preserved in the -80 ℃ refrigeratory. The tissues were classified into two groups： high sensitivity group （HS） and low sensitivity group （LS）, according to their response to radiotherapy. In the first part of our experiment, protein separating was performed by using two-dimensional gel electrophoresis （2-DE） with Amersham 18 cm linear pH 3-10 immobilized pH gradient （IPG） strips. The images of the gels were acquired by the scanner and then analyzed by using PD-quest7.3 software to find the differentially expression protein-spots in each group. Then the differentially expressed protein-spots was incised from the gels and digested by trypsin. The peptide mass fingerprintings （PMF） was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry （MALDI-TOF-MS） and the proteins were identified by data searching in the Mascot-database. Part of differentially expression proteins were assayed by Western Blot. Results： Most of the gels were clear and successfully analyzed by PD-quest7.3 software. Most of the protein-spots concentrated on the area of 20-100Kda （Mw） and pH4-8. The average number of the protein-spots was 754 ± 64 in HS group and 777 ±48个 in LS group. The match rate was 87.6% between two groups. Five high expression proteins were found in HS group which were low expression in LS group, 3 high expression protein were found in LS group which were low expression in HS group. Reselts of Western Blot were in coincidence to proteomic result. Conclusion： The 2-DE gels image of HS group and LS group with early cervical cancer tissues treated by radiotherapy are successfully acquired. Some differentially expression proteins between the two groups are further confirmed by immunohistochemical assay.展开更多
