OBJECTIVETo ascertain a clinically meaningful thermal dose unit-temperature equivalent minute (TEM) 42.5 degrees C and the relationship between TEM 42.5 degrees C and tumor response rate.
METHODSFrom August 1998 to December 2002, 49 patients with recurrent or metastatic malignancies in the pelvis were treated with hyperthermia combined with conventional radiotherapy. Direct thermometry with high resistance lead needle was used whenever possible to measure the temperature by inserting Teflon catheter into the tumor. TEM 42.5 degrees C was used as the thermal dose unit and the relationship between TEM 42.5 degrees C and tumor response rate was monitored.
RESULTSThere was a positive correlation between response rate TEM 42.5 degrees C and the radiation dose. The tumor volume and number of heat treatment showed no influence on response.
CONCLUSIONBoth univariate analysis and multivariate logistic regression analysis indicate that there is a positive correlation between the response rate, TEM 42.5 degrees C and the radiation dose. TEM 42.5 degrees C may act as a useful thermal dose unit in the combination of hyperthermia and radiotherapy. To lower the incidence of complications in thermometry, direct thermometry with high resistance lead needle can be used to measure the temperature by inserting Teflon catheter into the deep-seated malignancies.

OBJECTIVETo explore the clinical value and efficacy of reduced field intensity modulated radiation therapy (RF-IMRT) for patients with advanced cervical cancer.
METHODSSeventy-one patients with stage IIB-IIIB cervical cancer, who underwent reduced field IMRT (RF-IMRT group) and 72 patients treated with conventional radiotherapy (c-RT group) in Shandong Cancer Hospital between 2005 August and 2011 August, were enrolled in this study. The RF-IMRT plans were as follows: whole pelvic IMRT plan was performed to deliver an initial dose of 30 Gy, then the irradiated volume was reduced to lymphatic drainage region as well as paracervix and parametrium for an additional 30 Gy boost. Conventional 2-field RT plan was performed in these patients using ADAC Pinnacle 3 planning system, to be given the same prescription dose, and to compare the irradiation dose of organs at risk (OARs). At the same time, conventional 2-field RT was performed in 72 patients of the c-RT group. Concurrent chemotherapy and intracavitary brachytherapy were also performed in the two groups. The treatment response, toxicities, normal tissue avoidance, and survival were assessed.
RESULTSSixty-six patients of the RF-IMRT group and 65 patients of the c-RT group fulfilled the treatment plan. IMRT plans yielded better dose conformity to the target (0.711 ± 0.057 vs. 0.525 ± 0.062, P = 0.032) and better sparing of the rectum, bladder and small intestine (rectum: 41.6 ± 6.8 vs. 50.8 ± 3.2, P = 0.016; bladder: 40.2 ± 2.9 vs. 51.4 ± 1.8, P = 0.007; small intestine: 22.3 ± 2.6 vs. 35.8 ± 3.9, P = 0.004). The mean dose delivered to the planning target volume (PTV) was significantly higher in the RF-IMRT group than that in the c-RT group (60.8 vs. 51.2 Gy, P = 0.006). The RF-IMRT patients experienced significantly lower acute and chronic toxicities with comparable short-term effects than did those treated with conventional RT (P > 0.05). No significant differences were found between the two groups for 1-, 3-, and 5-year overall survival (OS) rates, while a significantly higher progression-free survival (PFS, 65.2% vs. 46.2%, P = 0.031) rate was observed in the RF-IMRT group.
CONCLUSIONSRF-IMRT yields higher dose distributions and lower toxicities compared with conventional RT, and both the tumor target volume and pelvic lymphatic drainage region achieve curative dose irradiation, the adjacent organs at risk are well protected, and with tolerable adverse reactions. Yet, RF-IMRT provides comparable clinical outcomes and higher PFS.

OBJECTIVETo investigate the clinical features, treatment outcomes and possible prognostic factors in elderly patients with cervical cancer.
METHODSClinical data of 215 elderly women (> or = 65-years-old) with cervical cancer were retrospectively analyzed. Most patients (89.3%) had advanced stage ( II b-IV) disease. Eight of the 215 patients (3.7%) underwent surgical treatment, and six of those received postoperative radiotherapy. 133 patients received radiotherapy alone, and 74 patients underwent concurrent chemotherapy and radiotherapy.
RESULTSThe median follow-up time was 48 months (range: 12-102 months). The overall 5-year survival rate was 63.7%. The 5-year survival rate for stage I, II, III, IV were 83.2%, 76.4%, 39.0% and 0, respectively. There was no significant difference in 5-year survival rate between patients treated with concurrent chemotherapy combined with radiotherapy and radiotherapy alone. In multivariate analysis, lymph node metastasis, advanced stage, non-squamous histologies and poor differentiation were all negative prognostic factors for the overall survival.
CONCLUSIONThe treatment strategy for elderly cervical cancer patients should be individually planned according to the disease stage and performance status of the patients. Usually, one radical therapy modality can be chosen, and combined modality therapy is not suggested.

OBJECTIVETo investigate the clinical application of diffusion weighted imaging (DWI) in uterine cervical cancer and the apparent diffusion coefficient (ADC) value in diagnosis and predicting treatment response.
METHODSTwenty-eight patients with advanced primary cervical cancer confirmed by pathology and 10 cases of normal uterine cervix as control were recruited in this prospective clinical trial. To analyze the correlation between tumor volume measured in DWI and tumor maximum diameter measured according to the RECIST criteria. To compare the ADC value differences among the uterine cervical cancer, uterine myometrium, and normal uterine cervix. To compare the ADC values in 17 cancer patients before and after treatment.
RESULTSThe illustration of tumor boundary in DWI was superior to conventional T2WI and post-enhancement T1WI. The DWI with higher b value (2000 s/mm(2)) had a better signal-to-noise ratio. The tumor volume measured in DWI has good correlation with tumor maximum diameter according to RECIST criteria (r = 0.759, P < 0.01). When b = 800 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium, and normal uterine cervix were (9.85 ± 1.55)×10(-3) mm(2)/s, (14.20 ± 2.80)×10(-3) mm(2)/s, and (14.14 ± 0.45) ×10(-3) mm(2)/s. When b = 2000 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium and normal uterine cervix were (7.38 ± 0.98)×10(-3) mm(2)/s, (8.52 ± 2.38)×10(-3) mm(2)/s, and (8.60 ± 0.63)×10(-3) mm(2)/s, respectively. There were significant differences between the cervical cancer and normal cervix or uterine myometrium (P < 0.001 for both). When b = 800 s/mm(2), the ADC value was (9.85 ± 1.55)×110(-3) mm(2)/s before and (13.41 ± 2.93)×10(-3) mm(2)/s after treatment (P < 0.001). When b = 2000 s/mm(2), the ADC value was (7.38 ± 0.98)×10(-3) mm(2)/s before and (8.93 ± 1.92)×10(-3) mm(2)/s after treatment (P = 0.008). Univariate logistic regression analysis showed that 25% ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were significantly correlated to the treatment outcome of cervical cancer (P < 0.05 for all). Multivariate regression analysis showed that 25%ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were not significantly correlated to the treatment outcome of cervical cancer (P > 0.05 for all). The values of ROC curves were 25%ADC = 0.818, 50%ADC = 0.775, and 75%ADC = 0.716 (P > 0.05), however, the 25% ADC showed a relatively stronger statistical power.
CONCLUSIONSDWI helps to confirm the morphology and exact target zone of the tumor for radiotherapy. DWI volume measurement is well correlated with RECIST criteria, particularly in volume measurement of irregular tumors. ADC value has a potential in quantitatively monitoring treatment response and predicting outcome of cervical cancers.

OBJECTIVE: To investigate the impact of pelvic radiation on survival in patients with uterine serous carcinoma (USC) who received adjuvant chemotherapy. METHODS: Patients with stage I-IV USC were identified from the Surveillance, Epidemiology, and End Results program 2000 to 2009. Patients were included if treated with surgery and chemotherapy. Patients were divided into two groups: those who received chemotherapy and pelvic radiation therapy (CT_RT) and those who received chemotherapy only (CT). Kaplan-Meier curves and Cox regression proportional hazard models were used. RESULTS: Of the 1,838 included patients, 1,272 (69%) were CT and 566 (31%) were CT_RT. Adjuvant radiation was associated with significant improvement in overall survival (OS; p<0.001) and disease-specific survival (DSS; p<0.001) for entire cohort. These findings were consistent for the impact of radiation on OS (p<0.001) and DSS (p<0.001) in advanced stage (III-IV) disease but not for early stage (I-II) disease (p=0.21 for OS and p=0.82 for DSS). In multivariable analysis adjusting for age, stage, race and extent of lymphadenectomy, adjuvant radiation was a significant predictor of OS and DSS for entire cohort (p=0.003 and p=0.05) and in subset of patients with stage III (p=0.02 and p=0.07) but not for patients with stage I (p=0.59 and p=0.49), II (p=0.83 and p=0.82), and IV USC (p=0.50 and p=0.96). Other predictors were stage, positive cytology, African American race and extent of lymphadenectomy. CONCLUSION: In USC patients who received adjuvant chemotherapy, adjuvant radiation was associated with significantly improved outcome in stage III disease but not for other stages. Positive cytology, extent of lymphadenectomy and African race were significant predictors of outcome.

OBJECTIVETo study the clinicopathologic features of uterine papillary serous carcinoma (UPSC) and the roles of adjuvant therapy.
METHODSSixty-one cases of UPSC with operation done and followed up for a period of 4 to 9 years were enrolled into the study. The histology of slides specimens were reviewed and immunohistochemical study was performed. The follow-up and survival data were analyzed.
RESULTSAll of the 61 patients were post-menopausal, with a median age of 68 years. The clinical presentations included abnormal vaginal bleeding, abdominal symptoms and abnormal Pap smears. The median size of the tumors was 7.5 cm (range=1.2 to 14.8 cm). There were 27.9% cases in FIGO stage I (8.2% in stage IA, 14.8% in stage IB and 4.9% in stage IC), 9.8% in stage II, 32.8% in stage III and 29.5% in FIGO stage IV. The histologic features were similar to those of the ovarian counterpart, with tumor cells containing the high-grade nuclei and arranged in complex papillae. Psammoma bodies were identified in 24.6% of the cases. Immunohistochemical study showed that the tumor cells demonstrated diffuse and strong nuclear staining for p53 and Ki-67. They were negative for estrogen receptor and progesterone receptor. Fifteen of the 61 cases (24.6%) showed no evidence of myometrial invasion. However, ten of the 15 cases had extrauterine disease, with peritoneal (6/15) and nodal (9/15) involvement. Tumors with deep myometrial invasion, lymphovascular permeation and nodal metastasis were associated with worse prognosis by univariate analysis. Fifty-six patients received adjuvant therapy. The number of patients receiving adjuvant chemotherapy alone, adjuvant radiotherapy alone and combined adjuvant chemotherapy/radiotherapy were 42, 24 and 10, respectively. The median survivals of the chemotherapy group and non-chemotherapy group (with or without radiotherapy) were 66.4 months and 32.8 months, respectively.
CONCLUSIONSUPSC has distinctive clinical and pathologic features. The tumor stage, lymph node status, lymphovascular permeation and depth of myometrial invasion were important prognostic factors. Adjuvant chemotherapy for stage III/IV tumors or recurrent UPSC may have survival benefit.

OBJECTIVETo analyze the clinical characteristics, influencing factors and outcome of recurrent patients with early stage bulky cervical carcinoma.
METHODSBetween January 1(st) 2000 and December 31(st) 2009, 76 patients with stage Ib2 and IIa2 bulky cervical carcinoma developed recurrence and (or) metastasis. The recurrence time, recurrence location, recurrence-related factors, treatment and survival were analyzed.
RESULTSThe median follow up was 44 months (9-137 months). The overall recurrence and (or) metastasis rate was 22.6%. The 1-, 1-2, 3-5 and 5-year recurrence and (or) metastasis rates were 38.2%, 27.6%, 30.3% and 3.9%, respectively. The 5-year survival rate of local recurrence was 34.5%, that of distant metastasis was 23.6%, and that of distant metastasis with synchronous pelvic recurrence was 11.1%, (P = 0.555). The 5-year survival rate of patients who received surgery plus chemotherapy, radiation plus chemotherapy and chemotherapy alone after recurrence and (or) metastasis were 53.3%, 30.7% and 24.6%, respectively (P = 0.686). Univariate analysis demonstrated that tumor recurrence and (or) metastasis in patients of the stage Ib2 and IIa2 bulky cervical carcinoma were influenced by the disease stage, pelvic lymph node metastasis, deep cervical stromal invasion, lymphovascular tumor thrombus and pathological types. Multivariate regression analysis demonstrated that pelvic lymph node metastasis, lymphovascular tumor thrombus and pathological types were the key factors affecting the recurrence and (or) metastases of the stage Ib2 and IIa2 bulky cervical carcinoma. Subgroup analysis showed that pelvic lymph node metastasis and stage were the main factors affecting the local recurrence in those patients, and the pathological type, vascular tumor thrombus and pelvic lymph node metastasis were the main factors affecting the distant metastasis.
CONCLUSIONSRecurrence and(or) metastasis of early stage bulky cervical cancer are mostly happened within 2 years post operation. Patients with pelvic lymph node metastasis have high probability to develop local recurrence and distant metastasis. Patients with non-squamous cell carcinoma and lymphovascular tumor thrombus are more likely to develop distant metastasis. Neoadjuvant chemotherapy does not decrease local recurrence and distant metastasis in patients with stage Ib2 and IIa2 bulky cervical carcinoma. Individualized treatment is advised for recurrent patients.

OBJECTIVE: This is a retrospective study aimed at clarifying the details of recurrence patterns and sites in patients with cervical cancer treated with definitive radiation therapy (RT). METHODS: Data were analyzed from consecutive patients, admitted to the University of Tokyo Hospital (Tokyo, Japan) between 2001 and 2013, who had received definitive RT, with or without chemotherapy, for International Federation of Gynecology and Obstetrics stages IB-IVA cervical cancer. RESULTS: One hundred and thirty-seven patients formed the patient cohort. The median follow-up period for surviving patients was 57.0 months. A complete response was achieved in 121 patients (88%). Of these, 36 (30%) developed a cancer recurrence during follow-up. The first sites of recurrence were located in intra-RT fields in nine, outside RT fields in 20, and both in seven patients. In the intra-RT field group, all patients showed a local recurrence, while no one experienced an isolated pelvic lymph node (PLN) recurrence. In the outside RT field group, the most frequent site of recurrence was lung (60%), and three-quarters of patients were free from intra-RT field recurrence until the last follow-up. Of the entire cohort, including 48 PLN-positive patients, only seven patients (5.1%) developed PLN persistence or recurrence, all in the common iliac, internal iliac, and/or obturator nodes, and all with another synchronous relapse. CONCLUSION: Local disease was a major type of intra-RT field recurrence, while PLN control was favorable even in initially PLN-positive patients. The predominance of outside RT field recurrence alone highlights issues concerning distant control, including the intensity enhancement of systematic therapy.
