RESUMEN

OBJECTIVES: Prostate cancer is a common form of cancer among men worldwide. The objective of this study was to conduct a systematic review of the economic evaluations of prostate cancer treatment strategies. METHODS: This systematic review was conducted using multiple electronic databases up to May 2021. English-language economic evaluation studies that compared intensity-modulated radiation therapy (IMRT), 3-dimensional conformal radiation therapy (3DCRT), and radical prostatectomy (RP) were included. The studies were evaluated using the Consolidated Health Economic Evaluation Reporting Standards checklist. The search yielded 1151 potentially relevant publications, which were screened based on the title and abstract. After the removal of duplicates, 55 studies remained, and 9 studies were screened in full text. Finally, textual data were analyzed manually using by-content analysis method. RESULTS: All studies were cost-effective and evaluated quality-adjusted life year as the efficacy indicator. The studies were conducted from either payers' or health systems' perspectives, and the time horizon varied from 5 to 20 years. We included only full economic evaluation studies. The use of IMRT in comparison with 3DCRT was evaluated in 6 studies, based on which IMRT increased health and reduced side effects of treatment. According to incremental cost-effectiveness ratio (ICER) results, IMRT was more cost-effective than 3DCRT. Three studies evaluated the use of RP in comparison with radiotherapy. Based on these studies, radiotherapy was more effective than RP. CONCLUSION: IMRT was found to be more cost-effective than 3DCRT in all 6 studies compared with the threshold. Radiotherapy was found to be more effective than RP. However, long-term clinical trial studies are needed to confirm these findings and to provide more definitive conclusions.

RESUMEN

Nested variant of urothelial carcinoma (NV-UC) is an extremely rare cancer with a nonspecific presentation. It is usually identified at a late stage, which makes the treatment challenging. Herein we report the case of a 52-year-old woman with an advanced NV-UC treated by anterior exenteration after a poor response to neoadjuvant chemotherapy. One year after completion of adjuvant radiotherapy, the patient remains disease-free.

RESUMEN

BACKGROUND: Leiomyosarcoma of visceral organs is uncommon, and pancreatic primary occurrence is even rarer. In terms of curative treatment, patients are generally managed with surgery alone, without significant data on the role or efficacy of adjuvant chemotherapy. CASE PRESENTATION: This manuscript presents a case of a 22-year-old female with advanced primary leiomyosarcoma of the pancreas, treated with radical surgery and adjuvant radiation therapy. CONCLUSION: With a low-survival rate, consideration of radiation therapy in some advanced and unresectable cases could be potentially beneficial.

RESUMEN

Introduction: No standard method has been defined to evaluate the therapeutic response of esophageal cancer to neoadjuvant chemoradiotherapy (CRT). This study aimed to determine the predictive value of endoscopic evaluation and biopsy after CRT in predicting the complete pathological response to neoadjuvant CRT in patients with esophageal squamous cell carcinoma (SCC). Materials and Method: This prospective, descriptive study was conducted on patients with stage II and III esophageal SCC who could undergo esophagectomy. Patients underwent neoadjuvant CRT. Four to six weeks after the end of treatment, re-endoscopy was performed and a biopsy was taken in the presence of a tumor lesion. In the absence of a tumor lesion, the marked site of the esophagus was removed as a blind biopsy. Gastrologist observations during endoscopy and the result of the pathological examination of an endoscopic biopsy were recorded. The patient underwent esophagectomy. The pathology obtained from endoscopic biopsy was compared with the pathology response obtained from esophagectomy. Results: Sixty-nine patients were included in the study, of which 32 underwent esophagectomy. In an endoscopic examination after CRT, 28 patients had macroscopic tumor remnants and 4 patients did not. Pathological examination of the samples obtained from endoscopy showed no tumor remnants in 10 patients (31.3%), and in 22 patients (68.7%), living tumor remnants were seen in the biopsy specimen. Pathologic evaluation of the samples obtained by surgical resection showed that in 13 patients, there were no viable carcinomas in the esophagus or lymph nodes removed, and the rate of pathologic complete response was 40.6. Sensitivity, specificity, positive predictive, and negative predictive values of endoscopic observations were 94.7, 23, 64.2, and 75%, respectively. Preoperative biopsy sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 68.4, 30.7, 59, and 40%, respectively. Conclusion: Considering the negative and positive predictive values of endoscopic observations and biopsy after neoadjuvant CRT, it seems that these two methods alone are not suitable for assessing the pathologic complete response after neoadjuvant treatment.

RESUMEN

PURPOSE: In this clinical trial, we evaluated Alpha® ointment efficacy in prevention of capecitabine induced hand-foot syndrome (HFS) in patients with gastrointestinal or breast cancers, for the first time. METHODS: During this pilot, randomized, triple-blinded, placebo-controlled clinical trial, the effect of Alpha® ointment (Lawsonia inermis 3 g and Curcuma longa 0.15 g/ 30 g) was assessed. It was applied on the palms and the soles, two times daily starting at the first day of chemotherapy for 4 consecutive courses. The severity of HFS was assessed at the end of the chemotherapy courses based on World Health Organization (WHO) scale and scored between 0-4. RESULTS: Ninety eligible patients were included randomly in the treatment or placebo group. Median WHO HFS grade was not significantly different between the two groups, during the follow-up period (P > 0.05). In the weekly assessment, the scores increased meaningfully in both the placebo and treatment groups, but there was a delay in HFS occurrence and deterioration in Alpha ointment group based on post hoc analysis. CONCLUSION: Administration of Alpha® ointment containing henna and curcumin could not significantly prevent capecitabine induced HFS during 4 courses of treatment, but can somewhat delay its occurrence in patients with gastrointestinal or breast cancer.

RESUMEN

OBJECTIVE: Previous clinical trials have suggested that herbal medicines can improve the quality of life (QOL) and survival of cancer patients. This study was aimed to evaluate the effects of a polyherbal compound (PHC, formulated as syrup) consisting of Allium sativum, Curcuma longa, Panax ginseng, and Camellia sinensis on the quality of life (QOL) and survival in patients with upper gastrointestinal cancers. MATERIALS AND METHODS: A randomized placebo-controlled trial was carried out on patients with esophageal or gastric cancer who had finished their oncological treatments. The patients were randomly assigned to PHC (n=20) or placebo (n=20) group. The PHC group was treated with the PHC for 12 weeks, while the placebo group received 70% sucrose syrup. The QOL was assessed at baseline and after 12 weeks. The patients were followed for up to 24 months to determine overall survival. RESULTS: PHC significantly improved cancer-related symptoms, physical performance, and psychological and social functions of the patients (p<0.05 for all cases). Death occurred in 33 and 22% of cases in the placebo and PHC group, respectively. The mean survival time was 16.8 months (95% CI: 12.8-20.9) in the placebo group and 21.4 months (95% CI: 19.1-23.6) in the PHC group but the difference was not statistically significant. CONCLUSION: The PHC improved cancer-related symptoms, physical performance, and psychological and social functions in patients with gastrointestinal cancers. It seems that this herbal compound has the potential to be used as a supplement in the management of cancer.

RESUMEN

Using standardized forms for prescription and administration of medications is one of the main solutions for reducing medication errors in the chemotherapy process. Considering the high prevalence and mortality rate of colorectal cancer, in this study we tried to design and validate a standard printed form and evaluate oncologists' and nurses' adherence to this form. This cross-sectional study was performed in Omid hospital, Mashhad, Iran from January 2015 to October 2015. A Chemotherapy form including various demographic and clinical parameters and approved chemotherapy regimens for colorectal cancer was designed by the clinical pharmacist and validated by clinical oncologists working in this center. All eligible patients admitted in this center during this period of time were included in the study. Adherence of the oncologists and nurses to this form and probable medication errors were identified by the pharmacy student. Sixty-seven patients with colorectal cancer and a total of 251 chemotherapy courses were evaluated. All patients received regimens compatible with developed form but in 206 courses (98.56%) of chemotherapy dosing error happened and in most of cases patients received lower than calculated dose (37.8%). Three errors occurred in administration step by nurses which they infused the medication in shorter than recommended duration. In general, oncologists' adherence with developed form for chemotherapy of colorectal cancer was relatively high, except in dose calculation. Avoiding from rounding the calculated medications' doses and precise calculation of patients' body surface area can prevent most of medication errors and reduce risk of adverse drug reaction occurrence.

RESUMEN

The current treatment approaches for esophageal cancer are associated with poor survival, and there are ongoing efforts to find new and more effective therapeutic strategies. There are several reports on the antitumoral effects of low-molecular-weight heparins (LMWHs). We have assessed the possible survival benefit of LMWHs in esophageal malignancies. This was a randomized, single-blind, multicenter, Phase II clinical trial on nonmetastatic esophageal cancer candidate for neoadjuvant chemoradiotherapy. Patients were randomly assigned to the chemoradiotherapy-only arm or chemoradiotherapy plus enoxaparin arm using 1:1 allocation. Radiotherapy was delivered in 1.8-Gy daily fractions to a dose of 50.4 Gy in both groups. Paclitaxel 50 mg/m2 and carboplatin (AUC 2) were administered weekly, concurrent with radiotherapy. In the intervention group, patients received enoxaparin (40 mg) and chemoradiation daily. 4-6 weeks after treatment, all patients underwent esophagectomy. After a median follow up of 7 months, estimated 1 year disease-free survival (DFS) in the intervention group was 78.9% and was 70% in the control groups ( p = 0.5). Toxicity from the experimental treatment was minimal, and there were no treatment-related deaths. A pathologically complete response in intervention and control group was 64.8% and 62.5%, respectively ( p = 0.9). There was a nonsignificant trend toward improved survival by the addition of enoxaparin to the concurrent chemoradiotherapy regimen. However, 1 y DFS of both groups were high as expected. A longer follow-up and a larger sample size are required.

RESUMEN

PURPOSE: Local recurrence is a common failure pattern in adenocarcinoma of the cecum. This study aimed to investigate the potential role of adjuvant radiation therapy on oncologic outcomes of patients with adenocarcinoma of the cecum. MATERIALS AND METHODS: This retrospective study was carried out at three large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of 162 patients with adenocarcinoma of the cecum that were treated and followed up between 2000 and 2013. All the patients had undergone a right hemicolectomy and received chemotherapy with (n = 48) or without (n = 114) adjuvant radiation therapy. RESULTS: The subjects were 65 females and 97 males with a median age of 56 years (range, 17 to 90 years) at diagnosis. The 5-year local control (LC), disease free survival (DFS), and overall survival (OS) rates were 72.7%, 57.2%, and 62.6% respectively. In a multivariate analysis, age, tumor stage, node stage, and adjuvant radiation therapy were determined to be independent prognostic factors. Age more than 55 years (hazard ratio [HR] = 1.0; 95% confidence interval [CI], 0.06-0.32; p = 0.003], T4 stage (HR = 6.8; 95% CI, 3.07-15.36; p < 0.001), node positive disease (HR = 4.2; 95% CI, 1.94-9.13; p < 0.001), and the absence of adjuvant radiation therapy (HR = 3.0; 95% CI, 1.39-6.46; p = 0.005) had a negative influence on OS. CONCLUSION: Adjuvant radiation therapy significantly improves DFS and OS in patients with adenocarcinoma of the cecum.

RESUMEN

Sentinel node mapping is an integral part of regional lymph node staging in many solid tumors and plays an important role in surgical oncology. This technique has been used with excellent results for non-melanoma skin cancers including Merkel Cell Carcinoma (MCC). In the current study, we reported our first MCC patient who underwent successful sentinel node mapping. We also reviewed the available literature regarding the prognostic significance of sentinel node mapping in cN0 MCC patients.

RESUMEN

Leptomeningeal carcinomatosis (LMC) from gastrointestinal cancer would be rare. A 56-years old man with complaint of dyspepsia and histopathologic examination of the biopsy specimens has shown: adenocarcinoma. At the end of adjuvant chemo radiation therapy, the patient has affected by headache and mild confusion. In cerebrospinal fluid (CSF) cytology, a plenty of malignant cells have seen and unfortunately after a short time for about 4 days after ICU admission, the patient has died. This could be due to heavy burden of disease in central nervous system.

RESUMEN

BACKGROUND: Breast carcinoma is the most common non-skin malignancy in women. More recently, it has been suggested that extracellular proteinase has also regulated growth factors and cytokines that might contribute to tumor progression. CD10 is a 90-110kd cell surface zinc-dependent metalloproteinase. Since CD10 is structurally similar to matrix metalloproteinase and stromelysin, it might facilitate cancer cell invasion and/or metastasis. The aim of this study was investigation the rate of CD10 expression in the stromal cells of invasive ductal breast carcinomas, Immunohistochemical aspects, then any other aspects to be able to clarify its correlation with other clinicopathological factors of this disease. METHODS: One hundred patients with histopathologic diagnosis of invasive ductal carcinoma and 50 patients with fibroadenoma of breast (as the control group) have selected, then 150 paraffin blocks have obtained. The stained slides by immunohistochemistry method for CD10 marker have examined separately by two pathologists, and discrepancies have reviewed in common session to get the final result. RESULTS: Stromal CD10 has detected in 28% of the IDC. No kind of immunoreactivity has identified in the stromal cells of normal breast. Stromal CD10 expression in IDC has significantly correlated with increasing tumor size (p<0.001), increasing histologic grade (p<0.001), the presence of nodal metastases (p<0.001) and estrogen receptor negative status (p=0.003). CONCLUSION: Stromal CD10 expression in IDC has closely correlated with invasion and metastasis and it might play an important role in the pathogenesis of IDC.

RESUMEN

BACKGROUND: Being diagnosed with cancer has major impacts on a patient's life. This study was conducted to explore how specific daily activities of patients change as a result of cancer diagnosis or its treatment and how these patients feel about such changes. METHODS: This was a cross-sectional descriptive study. Cancer patients referred to our clinics and by completing a questionnaire, they reported their daily activities and how they changed after diagnosis. A total of 201 patients in Canada and 167 patients in Iran completed the questionnaire. The research setting was the outpatient cancer clinics of the Jewish General Hospital in Montreal, Canada (February to April 2008) and Imam Reza Hospital and Ghaem Hospital in Mashhad, Iran (March to August 2008). RESULTS: More than 40 percent of the patients reported changes after the diagnosis in at least 8 out of 22 daily activities listed in the questionnaire. While a negative perception towards the changes was more common, some patients also perceived some changes as positive. More than half of the participants (56.9%) who were employed at the time of diagnosis experienced changes in the amount or type of their paid work after being diagnosed with cancer. CONCLUSION: The impact of a cancer diagnosis and treatment on a patient's daily activities is drastic. There is a need to provide support and interventions to help patients maintain daily activities they need and/or like. Further studies are needed to better understand the nature of such interventions.

RESUMEN

BACKGROUND: In this study we have evaluated the prognostic impact of Metastatic Lymph node Ratio (MLR) in gastric cancer patients whose have undergone curative surgical resection. METHODS: A total of 121 patients with gastric adenocarcinoma undergoing curative surgical resection (R0) in our institutions between 2003 and 2010 have been included in this study. MLR has classified into 3 groups as follows: MLR0; 0, MLR1; >0-0.33 and MLR2; 0.34-1. We have used Kaplan-Meier method to calculate survival rates and log rank test to compare survival curves between groups. Cox proportional hazards model has utilized for multivariate analysis. RESULTS: The median age of patients was 65 (range; 32 to 89) with a male to female ratio of 91/30 (3.03). 88 patients have undergone total gastrectomy (72.5%) and 33 subtotal gastrectomy (27.5%). With a median total retrieved lymph node of 11 (range; 6 to 44), the MLR0 to MLR2 has calculated in 28(23.1%), 31(25.6%) and 62 (51.2%) patients respectively. MLR2 (>0.33) has significantly associated with higher Tumor stage (T1-T2: 18.7% vs. T3: 56.2%, p=0.002). With a median follow up time of 12 months (range; 2-88), the 3-year survival in patients with MLR0, MLR1 and MLR2 was 75.1%, 54.8% and 9.5% respectively (p value<0.001). Tumor location (p<0.01), tumor stage (p<0.01) and lymph node stage (p<0.001) were also significant predictor of survival. MLR has also significant correlated with survival in 91 patients with less than 15 obtained lymph nodes (p<0.001). Cox-regression multivariate analysis has shown MLR as the most important and independent predictor of survival (p<0.001). CONCLUSION: MLR with cutoff point of 0.33 could be used as an independent prognostic factor in gastric cancer patients whose have undergone curative surgical resection. This factor could effectively predict survival even in cases with insufficient (<15) retrieved lymph nodes.

RESUMEN

BACKGROUND: Not all patients with non-small cell lung carcinoma (NSCLC) have mediastinal lymph node involvement and development of less invasive methods for evaluating mediastinal lymph nodes is important. Sentinel node biopsy has been used for NSCLC since 1999 to decrease the need for mediastinal lymph node dissection. In this review, we searched the literature in this regard and reported the results in a meta-analysis format. METHODS: Medline, SCOPUS, and ISI web of knowledge were searched using: "(lung AND sentinel)" with no date or language limit. Any study with more than 5 patients and enough information to calculate detection rate and sensitivity was included. RESULTS: Overall 47 and 43 studies (including subgroups) had the criteria for detection rate and sensitivity pooling respectively. Pooled detection rate was 80.6% [76.8-84%] and pooled sensitivity was 87% [83-90%]. Using radiotracers or both radiotracers and dyes had higher detection rate and sensitivity compared to dye alone. Among studies using radiotracers, highest detection rate was in intra-operative peri-tumoral injection group and highest sensitivity was in peri-tumoral pre-operative injection group. Emerging methods of sentinel node surgery including magnetic materials, fluorescent dyes, CT contrast agents, and carbon nano-particles had promising results. CONCLUSIONS: Sentinel node mapping using radiotracers is a feasible technique for mediastinal lymph node staging of N0 NSCLC patients. Alternative methods of sentinel node mapping are promising and warrant further studies.

RESUMEN

BACKGROUND: Chemotherapy-induced amenorrhea is one of long term side effects of adjuvant chemotherapy in patients with breast cancer which may interfere with their future reproductive function. Although amenorrhea is well recognized, the actual incidence following taxanes remains uncertain. METHODS: In a cross sectional study, we identified breast cancer patients aged 45 years or younger who were treated with adjuvant anthracycline and taxane-based regimens at three different oncology departments from 2001-2008. RESULTS: One hundred and nineteen patients met all eligibility criteria and consented to participate in a regular follow up program. The median age at diagnosis was 33.5 years (range, 25-41). Seventy (58%) patients developed amenorrhea for at least 12 months following completion of treatment, and regular menses were maintained in another 49 (42%) patients. No statistically significant association was found between age and development of amenorrhea, although those who experienced cessation of menses were older. CONCLUSION: Although taxane containing chemotherapy was associated with higher rate of amenorrhea compared to FAC, this was not statistically significant (P=0.11). Also, treatment with tamoxifen and Estrogen Receptor (ER) positive status was significantly correlated with chemotherapy induced amenorrhea.

RESUMEN

AIM: Based on previous investigations, the progress of gastritis may lead to gastric carcinomas. In some epithelial tumors, macrophage migration inhibitory factor (MIF), which is an inflammatory cytokine may inactivate p53 and play a role in tumorigenesis process. We decided to evaluate clinicopathological significance of MIF expression and the relation between p53 and MIF expressions in gastric adenocarcinomas. METHODS: Seventy-three consecutive cases of gastric adenocarcinomas, the tissue samples of which were available, were included in this study. Tissue sections were stained for MIF and p53 expression by immunohistochemistry and the expression was defined as positive (for more than 10%) and negative (for less than 10%) groups. Location of the tumor, histological subtypes, and grade of the tumor were determined by using routine H&E staining. Distant metastasis, lymph node involvement, and consequently the stage of tumor were specified. The patients' age and gender were obtained from their medical records. The relationship between expression of MIF and these variables was determined. RESULTS: Overexpression of MIF was observed in the cytoplasm of cancer cells in 46.6% (34/73) of cases and nuclear immunostaining of p53 was observed in 37% (27/73) of cases. Expression of MIF was significantly correlated with the location of tumor, but this expression has no statistically significant correlation with variables including: age, gender histological subtypes, distant metastasis, and lymph node involvement, stage and grade of the tumor, and p53 tumor suppressor gene expression. CONCLUSIONS: Our study suggests that MIF in gastric adenocarcinomas versus many other epithelial tumors cannot have a prominent role in tumor progress and inactivation of p53 tumor suppressor gene.

RESUMEN

AIM: To evaluate the relation of cluster of differentiation 44 (CD44) expression with clinicopathological features of gastric adenocarcinoma, and also its effect on prognosis with an emphasis on the differences between intestinal and diffuse types. METHODS: From 2000 to 2006, 100 patients with gastric adenocarcinoma, who had undergone total or subtotal gastrectomy without any prior treatment, were studied. Haematoxylin and eosin (HE) staining was used for histological evaluation, including the type (Lauren's classification) and grading of the tumor. The expression of CD44 in the gastric adenocarcinoma mucosa and the adjacent mucosa were determined by immunohistochemistry. The survival analysis was obtained using the Kaplan-Meier test. RESULTS: Of 100 patients, 74 (74%) patients were male. The tumors were categorized as intestinal type (78%) or diffuse type (22%). Sixty-five percent of patients were CD44-positive. CD44 expression was not detected in normal gastric mucosa. Rather, CD44 was more commonly expressed in the intestinal subtype (P=0.002). A significant relation was seen between the grade of tumor and the expression of CD44 (P=0.014). The survival analysis showed a poor prognosis of patients with CD44-positive tumors (P=0.008); and this was more prominent in the intestinal (P=0.001) rather than diffuse type. CONCLUSION: Cell adhesion molecule CD44 is highly expressed in gastric adenocarcinoma. CD44 expression is correlated with a poor prognosis in patients with the intestinal type of gastric adenocarcinoma. CD44 can, therefore, be utilized as a prognostic marker for this group of patients.

RESUMEN

OBJECTIVE: The human epidermal growth factor receptor-2 (HER-2)/neu is a proto-oncogene that is amplified in 10-30% of breast cancers. It is known to be associated with a poor overall survival. We studied the relationship between its amplification and different histological gradings of breast cancer. METHODS: We studied 196 patients diagnosed with breast cancer in 2005 at the Omid and Ghaem Training Hospital, Mashhad Medical University, Iran. The HER-2/neu oncoprotein was measured by immunohistochemistry and the histological gradings were carried out according to the Bloom-Richardson Grading system. RESULTS: Sixty-seven (34.2%) cases were HER-2/neu positive and 129 (65.8%) cases were HER-2/neu negative. Overexpression of HER-2/neu was significantly higher in breast cancer patients <30 years (50% versus 33.3%, p=0.034). There was a non-significant statistical relationship between histological grading and overexpression of HER-2/neu oncogen (p=0.087). Twelve (17.5%) of HER-2/neu positive cases were metastatic and only 4 (3.1%) of HER-2/neu negative cases had metastasis (p=0.051). CONCLUSION: HER-2/neu gene amplification or its overexpression is detected in approximately 34.2% of breast cancer cases. Patients with HER-2/neu positive breast cancer have higher stage and grade diseases. This may help to use a better treatment for patients.
