PURPOSE: To investigate the expression of cyclooxygenase (COX-2) and its association with clinicopathologic parameters and clinical outcome in patients with cervical cancer. PATIENTS AND METHODS: The study included 84 patients with stage IB to IVA cervical cancer. Patients with early-stage cases (n = 21) underwent radical surgery, whereas patients with locally advanced cervical cancer (LACC) (n = 63) were first administered neoadjuvant cisplatin-based treatment and subjected to surgery in case of response. Immunohistochemical analysis was performed on paraffin-embedded sections with rabbit antiserum against COX-2. RESULTS: COX-2–integrated density values in the overall population ranged from 1.2 to 82.3, with mean ± SE values of 27.4 ± 2.4. According to the chosen cutoff value, 36 (42.9%) of 84 patients were scored as COX-2 positive. COX-2 levels were shown to be highly associated with tumor susceptibility to neoadjuvant treatment. COX-2 showed a progressive increase from mean ± SE values of 19.9 ± 8.0 in complete responders through 31.5 ± 3.5 in partial responses to 44.8 ± 3.9 in patients who were not responsive (P = .0054). When logistic regression was applied, only advanced stage and COX-2 positivity retained independent roles in predicting a poor chance of response to treatment. COX-2–positive patients had a shorter overall survival (OS) rate than COX-2–negative patients. In patients with LACC, the 2-year OS rate was 38% in COX-2–positive versus 85% in COX-2–negative patients (P = .0001). In the multivariate analysis, only advanced stage and COX-2 positivity retained independent negative prognostic roles for OS. CONCLUSION: The assessment of COX-2 status could provide additional information to identify patients with cervical cancer with a poor chance of response to neoadjuvant treatment and unfavorable prognosis.

AbstractPurposeCervical cancer is the most common malignancy among women in Uganda. Most present with advanced disease, when hysterectomy is not possible and cure is less likely. This study reports the proportion recommended for hysterectomy and associated factors, recommended treatments by stage, and treatment uptake.MethodsWe conducted a prospective study among patients seeking care for cervical cancer at public referral hospitals in Uganda. In-person surveys were followed by a phone call. Descriptive and multivariate statistical analyses examined associations between predictors and outcomes.ResultsAmong 268 participants, 76% were diagnosed at an advanced stage (IIB-IVB). In total, 12% were recommended for hysterectomy. In adjusted analysis, living within 15 kilometers of Kampala (OR 3.10, 95% CI 1.20-8.03) and prior screening (OR 2.89, 95% CI 1.22-6.83) were significantly associated with surgical candidacy. Radiotherapy availability was not significantly associated with treatment recommendations for early-stage (IA-IIA) disease, but was associated with recommended treatment modality (chemo-radiation versus primary chemotherapy) for locally advanced stage (IIB-IIIB). Most (67%) had started treatment. No demographic or health factor, treatment recommendation, or radiation availability was associated with treatment initiation. Among those recommended for hysterectomy, 55% underwent surgery. Among those who had initiated treatment, 82% started the modality that was actually recommended.ConclusionWomen presented to public referral centers in Kampala with mostly advanced-stage cervical cancer and few were recommended for surgery. Lack of access to radiation did not significantly increase the proportion of early-stage cancers recommended for hysterectomy.

Abstract Background/aimWhile the treatment for early stage rectal cancer is surgery, when a diagnosis is made at a locally advanced stage, it is recommended to start treatment with neoadjuvant chemoradiotherapy. Therefore, it is important to determine which patients will respond best to neoadjuvant treatment. The aim of this study was to investigate which hematological, histopathological, and radiological parameters can predict the response to chemoradiotherapy. Methods and materialsA retrospective examination was made of 43 patients who underwent surgery following neoadjuvant chemoradiotherapy because of locally advanced stage rectal cancer. Demographic data were collected from the patient files, and the radiological, histopathological and laboratory findings before neoadjuvant chemoradiotherapy were compared with the findings after treatment. ResultsIn the postoperative evaluation, a pathological complete response was determined in 25.50% of the patients. Lymphovascular invasion, perineural invasion and absence of necrosisis were seen to be statistically related to major response (p<0.05), and in patients where the tumor was closer than 6cm to the anal verge, the response was betterConclusionWhen the findings were examined, histopathological lymphovascular invasion, perineural invasion, the presence of necrosis, and the anal verge distance were evaluated as parameters predicting the response to neoadjuvant chemoradiotherapy in rectal cancer.

Despite the recent advances in the management of cervical cancer using cisplatin-based concurrent chemoradiotherapy, substantial treatment failure still occurs, especially in advanced-stage patients and early-stage cervical cancer patients with high-risk prognostic factors. Therefore, efforts to further improve the survival and quality of life of these patients are necessary. Nedaplatin (cis-diammine-glycoplatinum), a derivative of cisplatin, was developed with the aim of producing a treatment with a similar effectiveness to cisplatin but decreased renal and gastrointestinal toxicities. Based on the promising results of preclinical studies, the clinical efficacy of nedaplatin as a radiosensitizing agent was evaluated in patients with cervical cancer. Retrospective analysis of nedaplatin-based concurrent chemoradiotherapy (CCRT) against cervical cancer suggested that nedaplatin-based CCRT can be considered as an alternative to cisplatin-based CCRT in both early-stage and advanced-stage cervical cancer patients. However, due to the lack of a randomized controlled study, nedaplatin-based CCRT has not been convincingly proven to be clinically effective in patients with cervical cancer. Further investigations in randomized controlled trials are therefore needed.

Background: There is a geographical, socioeconomical and logistic diversity among the cancer patients who reach a regional cancer center. In a developing economy like that of India's, only a minority of patients have medical insurance. So in our setup a cancer patient is met with time, distance and financial challenges. These intangible factors theoretically are expected to influence the ultimate outcome of cancer treatment. Aim: To evaluate the prevailing demographic and economic variables of cancer patients visiting our RCC and to look for any correlation among each other. Methods: The demographic details of cancer patients registered at our RCC between August 2017- September 2017 were retrieved retrospectively. Distance traveled to get to the RCC and get a diagnosis of cancer, time taken for diagnosis and initiation of treatment, and the source of finances for treatment were collected. A correlation among these factors was attempted to be identified. Statistical correlation was identified using Student t-test. Results: Among 591 patients who were analyzed, the median age of patient was 55 years old. The median time taken for the patient to reach the RCC from permanent residence after the beginning of cancer related complaints was 3.19 months. The median distance traveled for the same was 131 km. The source of income was private employment for 223 patients and government employment for 164 patients and self-employment for 200 patients. Only 164 patients had some kind of structured health scheme to manage their health care expenses. Among these, 96 patients had private insurance/reimbursement and 64 patients had government reimbursement. 384 (64%) of patients presented with advanced and locally advanced stage disease while 114 (19%) patients presented to us with early stage disease. However a correlation between delay in presentation to the RCC, distance traveled to reach the RCC, source of income and advanced stage of disease couldn't not be established. Conclusion: Majority of patients visiting our RCC is from far off places and most of these patients pay for the cancer treatment themselves without any support from government or private insurances. All these factors may be responsible for late or advanced stage presentation of cancer patients.
