RESUMEN

Background: Malignant melanoma (MM) is one of the most prevalent and deadliest forms of skin cancer, resulting from the malignant transformation of melanocytes. It accounts for approximately 1.7% of global cancer diagnoses and is the fifth most common cancer in the US. MM can metastasize to almost any part of the body, with early detection significantly improving prognosis. Case presentation: We report the case of an 81-year-old female with a history of malignant melanoma (primary lesion on the left calf) and various comorbidities. She presented with severe anemia of unknown origin. A CT scan was performed due to her medical history, revealing a circumferential, asymmetrical parietal thickening at the level of a hypogastric ileal loop. The lesion suggested a tumoral substrate. Subsequent colonoscopy showed no metastatic lesions, but surgical intervention confirmed a malignant melanoma ileal metastasis. The patient underwent laparoscopic segmental resection with favorable post-surgery outcomes. Histopathological examination of the resected tissue confirmed the diagnosis of small intestine secondary lesions from the malignant melanoma. Conclusion: This case underscores the necessity of considering metastatic melanoma in patients with a history of MM and vague gastrointestinal symptoms. Early and accurate diagnosis through advanced imaging and endoscopic techniques can significantly improve patient outcomes.

RESUMEN

BACKGROUND In the European Union, a tablet with fixed doses of ombitasvir, paritaprevir, and ritonavir combined with dasabuvir is an authorized treatment for patients with chronic hepatitis C virus (HCV) infection. Ribavirin is a broad-spectrum antiviral used in several treatment regimens for patients with HCV infection. This real-world study aimed to compare the safety and efficacy of ombitasvir, paritaprevir, and ritonavir combined with dasabuvir, with or without ribavirin, in 587 patients with chronic hepatitis C attending the Fundeni Clinical Institute, Bucharest, Romania. MATERIAL AND METHODS This is an observational prospective study including 315 patients with F4 degree of fibrosis and compensated cirrhosis, 185 patients with F3 fibrosis, and 83 patients with F2 fibrosis. Liver fibrosis was evaluated by liver biopsy or Fibromax. Efficacy was defined as undetectable HCV-RNA at 12 weeks after the end of treatment. In terms of safety, we monitored the development of adverse reactions, liver cytolysis, cholestasis, and hematologic disorders. RESULTS Of the 587 patients, 2 patients with B-cell lymphoma died during therapy. In total, 3/585 patients (0.51%) did not achieve sustained virologic response. Common adverse effects were nausea and asthenia (especially in patients with other medical treatments; P=0.03 and P=0.04, respectively) and anemia in patients who received ribavirin (P<0.01). None of the patients discontinued antiviral treatment. Patients with kidney transplant or end-stage kidney disease did not receive or discontinued ribavirin. CONCLUSIONS Ombitasvir, paritaprevir, and ritonavir combined with dasabuvir, with or without ribavirin had an efficacy rate of over 99% in HCV genotype 1b infection. We report no serious adverse reactions.

RESUMEN

INTRODUCTION: Chronic mesenteric ischemia is a rare entity with non-specific symptomatology; combined with rare etiologies, it could lead to unwarranted surgical indication. CASE REPORT: We report the case of an 85-year-old woman, with a history of hypertension, persistent thrombocytosis, atherosclerosis, and recent minor COVID-19 infection, presenting to the hospital with postprandial abdominal pain and nonspecific clinical examination findings; upon abdominal CT, superior mesenteric artery circumferential thrombosis was revealed. A bone marrow biopsy was performed due to suspected essential thrombocythemia, confirming the diagnosis. An endovascular approach was chosen as therapy option and a stent was placed in the occluded area. Dual antiplatelet and cytoreductive therapies were initiated after the intervention. Clinical course was excellent, with no residual stenosis 1 month after stenting. CONCLUSIONS: The therapeutic strategy in elderly patients with exacerbated chronic mesenteric ischemia requires an interdisciplinary approach in solving both the exacerbation and the underlying conditions in order to prevent further thrombotic events. Although the patient presented a thrombotic state, other specific risk factors such as COVID-19 related-coagulopathy and essential thrombocythemia should be considered.

RESUMEN

Background and Objectives: Cirrhotic cardiomyopathy is a chronic cardiac dysfunction associated with liver cirrhosis, in patients without previous heart disease, irrespective of the etiology of cirrhosis. Electrocardiography (ECG) is an important way to evaluate patients with cirrhosis and may reveal significant changes associated with liver disease. Our study aimed to evaluate ECG changes in patients with diagnosed liver cirrhosis and compare them to patients with chronic hepatitis. Materials and Methods: We evaluated laboratory findings and ECG tracings in 63 patients with cirrhosis and 54 patients with chronic hepatitis of viral etiology. The end points of the study were prolonged QT interval, QRS hypovoltage and T-peak-to-T-end decrease. We confirmed the diagnosis of cirrhotic cardiomyopathy using echocardiography data. Results: Advanced liver disease was associated with prolonged QT intervals. Also, QRS amplitude was lower in patients with decompensated cirrhosis than in patients with compensated liver disease. We found an accentuated deceleration of the T wave in patients with cirrhosis. These findings correlated to serum levels of albumin, cholesterol and ammonia. Conclusions: ECG changes in liver cirrhosis are frequently encountered and are important noninvasive markers for the presence of cirrhotic cardiomyopathy.

RESUMEN

Introduction: Extended pelvic resection might be the option of choice in patients presenting locally advanced cervical cancer. However, the possibility of a co-existence of an ectopic, pelvic kidney that is invaded by such a tumor is extremely rare. Case Presentation: A 54-year-old female patient, diagnosed with locally advanced cervical cancer in the presence of a pelvic kidney, was submitted to surgery with curative intent. A large, abscessed cervical tumor invading the urinary bladder and the rectum was found, so a total exenteration was planned. Intraoperatively, tumor invasion of the left kidney, which was found in an ectopic, pelvic position was also encountered; therefore, total pelvic exenteration in association with a left nephrectomy was successfully performed. Conclusions: The presence of an ectopic, pelvic disposition of the kidney makes it susceptible to be invaded by locally advanced pelvic tumors; in such cases, a nephrectomy might also be needed.

RESUMEN

Background/Aim: Synchronous gynecological malignancies are rarely encountered, and most often these cases are represented by synchronous ovarian and endometrial cancer. The aim of this paper is to present the case of a 53-year-old patient who was diagnosed with synchronous cervical and ovarian cancer. Case presentation: The patient had been initially investigated for vaginal bleeding and was submitted to a biopsy confirming the presence of a cervical adenocarcinoma. Once the diagnostic of malignancy was confirmed, the patient was submitted to a computed tomography which revealed the presence of large abdominal tumoral nodules of peritoneal carcinomatosis and was submitted to palliative chemotherapy with poor response. Eighteen months later she developed intestinal obstruction and was submitted to surgery. At that moment, synchronous ovarian and cervical tumors were diagnosed. Total radical hysterectomy with bilateral adnexectomy, pelvic and para-aortic lymph node dissection, omentectomy, and pelvic peritonectomy was performed; in the meantime, the histopathological studies confirmed the presence of two synchronous malignancies. Conclusion: Although synchronous lesions are rarely encountered, this eventuality should not be omitted. In such cases, surgery should be taken in consideration and the intent of radicality should regard both lesions.

RESUMEN

Background and objectives: To identify the risk factors for para-aortic lymph node metastases in cases with presumed early stage ovarian cancer. Materials and methods: Between 2014 and 2019, 48 patients with apparent early stage ovarian cancer were submitted to surgery. In all cases, pelvic and para-aortic lymph node dissection was performed for staging purposes. Results: Among the 48 cases we identified nine cases with positive pelvic lymph nodes and 11 cases with positive para-aortic lymph nodes. The positivity of the retrieved lymph nodes was significantly correlated with the histopathological subtype represented by serous histology (p = 0.02), as well as with the degree of differentiation (p = 0.004). Conclusion: Patients with serous ovarian carcinomas in association with a poorer degree of differentiation are at risk of associated lymph node metastases even in presumed early stages of the disease. Therefore, lymph node dissection should be performed in such cases in order to provide adequate staging and tailoring of further treatment.

RESUMEN

Introduction: The larvae of Echinococcus, a parasitic tapeworm, cause hydatid disease. The most commonly involved organ after the liver is the lung but there are cases of hydatid cysts in all systems and organs, such as brain, muscle tissue, adrenal glands, mediastinum and pleural cavity. Extra-pulmonary intrathoracic hydatidosis can be a diagnostic challenge and a plain chest x-ray can be misleading. It can also lead to severe complications such as anaphylactic shock or tension pneumothorax. The purpose of this paper is to present a severe case of primary pleural hydatidosis, as well as discussing the difficulties that come with it during diagnosis and treatment. Case Report: We present the case of a 43-year-old male, working as a shepherd, presenting with moderate dyspnea, chest pain and weight loss. Chest x-ray revealed an uncharacteristic massive right pleural effusion and thoracic computed tomography (CT) confirmed it, as well as revealing multiple cystic formations of various sizes and liquid density within the pleural fluid. Blood work confirmed our suspicion of pleural hydatidosis with an elevated eosinophil count, typical in parasite diseases. Surgery was performed by right lateral thoracotomy and consisted of removal of the hydatid fluid and cysts found in the pleura. Patient was discharged 13 days postoperative with Albendazole treatment. Conclusion: Cases of primary pleural hydatidosis are very rare but must be taken into consideration in patients from endemic regions with jobs that may have exposure to this parasite. Proper treatment, both surgical and antiparasitic medication, can lead to a full recovery and a low chance of recurrent disease.

RESUMEN

BACKGROUND: The Liver Imaging Reporting and Data System (LI-RADS) combines standardized terminology with a classification system for imaging findings in patients with HCC, therefore rendering diagnostic biopsy unnecessary in many cases. This retrospective study included 23 patients with a biopsy diagnosis of HCC, performed either before or after local interventional procedures, in order to evaluate the histopathologic changes induced by previous procedures and their potential influence on the response to immune therapy. MATERIAL AND METHODS: The study encompassed a cohort of patients diagnosed with Hepatocellular Carcinoma (HCC). Diagnosis was established via contrast-enhanced computer tomography or magnetic resonance imaging that identified LI-RADS-5 nodules in conjunction with historical liver disease and elevated alpha-fetoprotein (AFP) levels or via histological examination confirming positivity for glypican3, heat shock protein 70, and glutamine synthetase. The study detailed the liver disease etiology, LI-RADS scores, characteristics and dimensions of HCC nodules, serum AFP concentrations, Edmondson-Steiner grading, and the expression of programmed cell death ligand 1 (PD-L1) in the tumor cells. RESULTS: Among the study's cohort of Hepatocellular Carcinoma (HCC) patients, a portion had not received any prior treatments, while the remainder experienced local HCC recurrence following trans-arterial chemoembolization or radiofrequency ablation. Observations indicated elevated alpha-fetoprotein (AFP) levels in those who had not undergone any previous interventions, showing statistical significance. The Edmondson-Steiner classification predominantly identified grade III differentiation across patients, irrespective of their treatment history. Furthermore, an increase in intra-tumoral programmed cell death ligand 1 (PD-L1) expression was noted in patients who had not been subjected to previous therapies. CONCLUSION: Liver biopsy offers valuable insights for patients with Hepatocellular Carcinoma (HCC), assisting in the tailoring of immune therapy strategies, particularly in cases of recurrence following prior local interventions.

RESUMEN

Inflammatory liver diseases are, nowadays, multifactorial and wide-spread, thus having an important socio-economic impact. Although the therapeutic algorithms are well-known in hepatitis, regardless of etiology, strategies to identify inflammatory hepatic lesions in early stages and to develop new epigenetic therapies should be prioritized. The main entities of inflammatory liver disease are: alcoholic and non-alcoholic fatty liver disease, autoimmune hepatitis, viral hepatitis and Wilson disease. The main epigenetic processes include: DNA methylation/demethylation, which imply changes in DNA tertiary structure; post-translational histone covalent changes (methylation/demethylation, acetylation/deacetylation, ubiquitination), that cause DNA-histone instability; synthesis of small, non-coding RNA molecules, called microRNAs, that modulate translational potential of transcripts (mRNAs) and post-translational modification of polypeptide chains. Consequently, the epigenetic interactions aforementioned, play an important modulatory role in disease progression and response to conventional therapies The present review focused on the main epigenetic changes in inflammatory liver conditions, considering a new perspective: Epigenetic therapy. This approach is more than welcomed, taking into consideration that conventional therapeutic strategies are almost exhausted.

RESUMEN

BACKGROUND/AIM: Patients with hepatitis C virus (HCV)-associated cirrhosis are more prone to developing type 2 diabetes mellitus than patients with any other etiology of cirrhosis. The main objective of this study was to evaluate the impact of all oral antiviral treatment with ritonavir-boosted paritaprevir/ombitasvir and dasabuvir (OBV/PTV/r + DSV) in patients with chronic genotype 1b HCV infection. PATIENTS AND METHODS: We retrospectively evaluated 806 patients who underwent antiviral therapy between December 2015 and July 2019. The laboratory data analyzed were liver function tests, kidney function tests, HCV viremia, fasting glucose levels, and glycosylated hemoglobin. RESULTS: Patients with impaired glucose metabolism were predominantly male and of older age compared to patients with normal glucose tolerance, and also had higher levels of transaminases. Proteinuria and higher creatinine levels were found in patients with impaired glucose metabolism. Overall, we found a 98.01% rate of sustained virologic response (SVR), with a non-significant difference between patients with normal and abnormal glucose metabolism. A statistically significant difference in SVR rates in patients with low degrees of fibrosis (F0-F2) versus those with advanced degrees of fibrosis (F3-F4) was found in both groups. Antiviral treatment resulted in significant decreases in fasting glucose levels and glycosylated hemoglobin levels in all patients with impaired glucose metabolism at SVR. CONCLUSION: Patients with pre-diabetes, as well as diabetic patients, achieved a better glycemic control after SVR obtained by ritonavir-boosted paritaprevir/ombitasvir and dasabuvir.

RESUMEN

BACKGROUND AND AIMS: The sofosbuvir (SOF) / velpatasvir (VEL) / voxilaprevir (VOX) combination has been evaluated in more than 800 patients enrolled in phase II and phase III studies, where it demonstrated excellent safety and efficacy, achieving overall sustained viral response (SVR) rates of more than 95%. We aimed to assess the efficacy and safety of SOF/VEL/VOX in a real-world study, including patients previously treated for genotype 1b hepatitis C virus (HCV) infection that did not obtain a sustained viral response with previous direct-acting antivirals (DAAs) therapy. METHODS: In Romania, through a nationwide government-funded program in 2019-2020, 213 patients with chronic hepatitis C non-responders to previous DAAs therapy, received treatment with SOF/VEL/ VOX 400/100/100 mg/day for 12 weeks. We performed a retrospective longitudinal study that included 143 individuals who were treated in Bucharest, Iași, Craiova and Constanța clinics, all with genotype 1b HCV infection. Efficacy was assessed by the percentage of patients achieving SVR 12 weeks post-treatment (SVR12). Serious adverse events (SAE) were registered. RESULTS: Our cohort comprised 53% males with a median age of 60 years (27÷77); 47% were pre-treated with ombitasvir/paritaprevir/ritonavir+dasabuvir ± ribavirin, 40% with ledipasvir/SOF, 13% with elbasvir/ grazoprevir. 42% of patients associated co-morbidities, 45% had compensated liver cirrhosis, 2% had treated hepatocellular carcinoma (HCC) and 1% had hepatitis B virus co-infection. SVR by intention to treat was reported in 139/143 (97.2%) and per protocol in 141/143 (98.6%). No predictive factors for SVR were identified. Rate of liver decompensation in patients with cirrhosis was 6% and was statistically associated in multivariate analysis with Child-Pugh score (p<0.01) and with severe steatosis (p=0.004). Occurrence of new HCC was reported in 3.6% of all patients with cirrhosis and was associated with poor liver function [higher Child-Pugh score (p=0.001) and low albumin levels (p=0.02)]. Serious adverse events related to therapy were reported in 1/143(0.7%). CONCLUSIONS: SOF/VEL/VOX was highly efficient in our population of patients with a 97.2% SVR. Liver decompensation occurred in 6% of cirrhotic patients at SVR, related to hepatic dysfunction.

RESUMEN

BACKGROUND/AIM: The aim of this study was to determine the safety and efficacy of a direct-acting antiviral treatment, ombitasvir/paritaprevir/ritonavir and dasabuvir, without ribavirin, in a real-life setting. PATIENTS AND METHODS: We performed a prospective observational study including 108 patients undergoing hemodialysis for end-stage kidney disease, referred to our clinic for antiviral therapy for chronic hepatitis C virus infection. Patients received treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir, for 12 weeks. Sustained virologic response (SVR) was defined as undetectable viremia at 12 weeks after the end of therapy. For safety analysis, we monitored serum levels of hemoglobin, albumin, total bilirubin, alanine-aminotransferase and aspartate- aminotransferase at the beginning and end of therapy, as well as at SVR. Verbal Numeric Rating Scale was used to assess the presence of nausea, headaches and fatigue. RESULTS: We noted a high prevalence of diabetic and hypertensive nephropathy as the underlying cause of chronic kidney disease. Most of the patients had F2 and F3 liver fibrosis (32.40% and 34.25%, respectively). The SVR rate was 96.2% (103/107 patients). We recorded an unrelated death after the completion of antiviral therapy. We found increased levels of nausea, headaches and fatigue at the end of therapy compared to at initiation, The presence and degree of symptoms did not correlate with the underlying cause of renal disease (p=0.72) nor with the degree of fibrosis (p=0.08). Minimal increases in transaminases and bilirubin were recorded at the end of treatment, with no statistical significance. CONCLUSION: Oral antiviral therapy with ombitasvir/paritaprevir/ritonavir and dasabuvir can be safely used in hemodialysis patients, with similar response rates compared to the general population.

RESUMEN

BACKGROUND/AIM: In women, breast cancer is the most commonly diagnosed cancer type and at the same time the main cause of cancer-related death. Many mechanisms are involved in the tumor microenvironment to restrict the anti-tumor activity by the immune system. Identification of novel prognostic tools based on immunological data could make significant impact in developing innovative immunotherapy strategies that will restore the anti-tumor immune system efficacy. PATIENTS AND METHODS: The study was performed on patients diagnosed with breast cancer, who were divided into two groups depending on the expression of HER2. For the studied group, first we described the infiltrate inflammatory on slides stained with haematoxylin eosin (HE) and in the second part we used flow cytometry in order to measure the percentage of T lymphocytes from the peripheral blood before and after breast cancer treatment. RESULTS: High presence of tumor-infiltrating lymphocytes (TILs) was associated with prognostic improvement, better disease-free survival, distant disease-free survival and overall survival. In breast cancer, the presence of TILs predicts the full pathological response rate (pCR) after neoadjuvant chemotherapy. TILs are one of the best examples of the strict relationship existing between natural defence and carcinogenesis. CONCLUSION: Modulation of the immune system is a promising strategy in the treatment of breast cancer, especially in triple-negative and HER2-positive molecular subtypes, the most immunogenic subtypes with a poor prognosis.

RESUMEN

BACKGROUND/AIM: The Covid-19 epidemic has severely strained health care systems across the globe. The impacts are multiple especially for patients cared for cancer. The Covid-19 epidemic has several impacts on the management of lung cancer patients. The aim of this work was to summarize the available epidemiological data on patients diagnosed with lung cancer infected with Covid-19 and describe the different strategies to improve the management of these patients by summarizing the recommendations in this area. PATIENTS AND METHODS: The Teravolt cohort is an observational multicenter registry, including patients with non-small cell cancer, small cell cancer or mesothelioma but also epithelial tumors and a diagnosis of Covid-19. The Theravolt registry indicates an unexpectedly high mortality rate in patients with thoracic malignancies with COVID-19. RESULTS: Between March 26 and April 12, 2020, 200 patients treated in 8 countries were included. They had a performance status (PS) of 0-1 in 72% of cases, were smokers or ex-smokers in 81% of cases, had non-small cell cancer (76% of cases), were under treatment in 74% of cases, and the majority were first-line cases (57%). The hospitalization rate was 76% and the mortality rate 33%; only 10% of patients with criteria for intensive care hospitalization were admitted to the intensive care. CONCLUSION: Data presented in this registry suggest a high mortality in patients with thoracic cancer and Covid-19. Therofere, the importance to create a safe healthcare system during Covid-19 pandemic is underlined along with the need for essential effective clinical service delivery to patients with lung cancer.

RESUMEN

Immunotherapy using immune checkpoint inhibitors has revolutionized the treatment, and many types of cancer show a response rate of 20-40% and a significant increase in five-year survival. However, immunotherapy is expensive and may cause serious adverse events. Therefore, a predictive method allowing identification of responding patients before starting the treatment would be very useful. In this study, we aimed to identify and implement other individual prognosis factors, factors that could lead to an improved clinical decision made in regard to the patient to establish an individualized treatment. Materials and Methods. All patients recruited from October 2018 to July 2019 were treated in OncoFort Hospital, Bucharest, with nivolumab or pembrolizumab. We investigated T lymphocyte CD3+, CD4+, CD8+, and CD4/CD8 cells by flow cytometry in patients before and after receiving treatment with anti-PD-1 agents. Results. We found that the responder group showed higher expression on CD4+ cells than the nonresponder group after the first cycle of immunotherapy. The prediction of the immunotherapeutic effect revealed that the elevation of T lymphocytes CD8+ and CD4+ after the first cycle of immunotherapy was followed by a decrease in their expression after the second cycle and was followed by a return almost to that one after the first administration. Conclusion. Our work indicates that the evaluation of the cells of the immune system in relation to the tumor and immunotherapy may lead to a better understanding of the pathogenic mechanisms and the identification of prognostic and predictive factors that will more effectively model the therapeutic approach.

RESUMEN

Viral hepatitis C represents a significant liver pathology worldwide, with a detrimental impact on national health systems. The present study aimed to correlate the levels of serum α-fetoprotein (AFP) with prognostic tools such as Fibroscan®, the presence of mixed cryoglobulinemia, and various demographic and standard biochemical markers, in patients with chronic hepatitis C, unrelated to hepatocellular carcinoma (HCC). A clinical study was designed considering three study groups: Hepatitis C virus (HCV) group including 35 patients with chronic hepatitis C and detectible viral load; sustained viral response (SVR) group including 20 HCV patients without detectable virus load 12 weeks after therapy cessation; a control group represented by 37 healthy volunteers. It was observed that serum AFP was moderately increased in the HCV and SVR groups and was positively correlated with aspartate transaminase (AST), alkaline phosphatase (AP), and γ-glutamyl transferase (GGT). The incidence of mixed cryoglobulinemia was increased in the HCV group, and the degree of fibrosis assessed by Fibroscan® was increased in both the HCV and SVR groups. In conclusion, the data revealed that a moderate increase in AFP levels could be present in patients with HCV even in the absence of HCC, unrelated to viral load or therapy response and that there was a linear positive correlation between serum levels of AFP and the degree of hepatic cytolysis and cholestasis. Additionally, mixed cryoglobulinemia was present in HCV patients with patent viral load, decreasing in those with SVR after therapy cessation unrelated to any renal impairment, while the degree of fibrosis was increased in HCV-infected patients, with no reversibility 12 weeks after successful therapy.

RESUMEN

ABSTRACT: Cervical cancer represents a general health issue spread all over the globe, which prompts the surge of scientific survey toward the rise of survival and condition of life of these patients. American and European guidelines suggest the open surgery, laparoscopic, and robotic surgery are the main therapeutic approaches for radical hysterectomy for patients with cervical cancer. This is the first survey to analyze the long-term oncological outcome of an extensive series of subjects cared for with multimodality treatment, here comprising robotic surgery.This study intents to evaluate the long-term oncological result in patients diagnosed with cervical cancer treated with radiotherapy (±chemotherapy) and robotic surgery compared with open surgery. Medical files of 56 patients diagnosed with cervical cancer who underwent a robotic hysterectomy and radiotherapy ± chemotherapy were retrospectively analyzed.The median age at diagnosis was 50.5 (range: 23-70). Eleven patients (19.6%) presented in an early stage (IB-IIA) and 80.4% advanced stage (IIB-IVA). Overall response rate after radiotherapy and chemoradiotherapy was 96.2%. Pathologic complete response was obtained in 64% of patients. After a median follow-up of 60 months (range: 6-105 months), 8 patients (14.2%) presented local recurrence or distant metastases. Disease-free survival (DFS) was 92% at 2 years and 84% at 3 and 5 years. Overall survival (OS) rates at 2, 3, and 5 years for patients with robotic surgery were 91%, 78%, and 73%, median OS not reached. OS was lower in the arm of open surgery (2, 3, and 5 years 87%, 71%, and 61%, respectively; median OS was 72 months P = .054). The multivariate analysis regarding the outcome of patients revealed an advantage for complete versus partial response (P < .002), for early versus advanced stages (P = .014) and a 10% gained in DFS at 3 years for patients in whom chemoradiotherapy was administered (DFS at 3 years 75% vs 85%) in patients with advanced stages.Robotic surgery has a favorable oncological outcome when associated with multimodal therapy.

RESUMEN

Pancreatic head cancer is frequently associated with invasion of the surrounding vascular structures, such cases being considered for a long period of time as unresectable. Improvement of the vascular surgery techniques allowed association of extended vascular resections and reconstructions, increasing in this way the percentage of patients benefiting from radical surgery. We present the case of a 47-year-old male patient with no significant medical history diagnosed with a large pancreatic head tumor invading the common and proper hepatic artery as well as the portal vein. The venous reconstruction was performed using a synthetic prosthesis while the left hepatic artery was sutured to the left gastric artery; meanwhile the right hepatic artery was reconstructed using the splenic artery. In conclusion, extended hepatic artery resection followed by arterial reconstruction in association with portal vein resection and prosthetic replacement might be needed in cases presenting large pancreatic head tumors with vascular invasion.

RESUMEN

Peritoneal carcinomatosis, as well as the presence of liver metastases from colorectal cancer, has been long considered as the sign of a systemic disease, transforming the patient into a candidate for palliation and best supportive care. However, in recent decades, progress in the field of medical and surgical oncology has allowed scientists worldwide to produce curative therapeutic strategies for these cases such as hyperthermic intraperitoneal chemotherapy (HIPEC) or extended liver resection. In addition, the association of these two therapies has also been performed with encouraging results. The aim of the current study was to review articles published thus far in regard to the association of these two therapeutic strategies, in order to identify which cases can benefit the most, which is the most efficient agent or combination of agents, and whether these types of therapy should be performed as monotherapy or as a two-stage procedure.
