Is There a Correlation Between Platelet Count, Mesenteric Lymph Node Involvement, and Hematogenous Metastases in Advanced Stage Ovarian Cancer?

BACKGROUND/AIM: Ovarian cancer remains a major cause of death in women worldwide, mainly due to late diagnosis and the lack of a reliable screening test for early detection of the disease. In this context, attention has been focused on the identification of other prognostic factors that might allow a better identification of cases with worse long-term outcome. PATIENTS AND METHODS: Data of patients who underwent cytoreductive surgery between 2014-2019 were retrospectively reviewed and 57 patients were considered eligible for this study. These cases were further classified according to preoperative platelet count, with a cut-off value of 335,000/µl as a positive predictive value for long-term survival. RESULTS: According to this value, there were 27 cases with a preoperative platelet count lower than 335,000/µl and 30 cases with a preoperative platelet count higher than 335,000/µl. Cases in the second group had a significantly higher peritoneal carcinomatosis index (p=0.002), a higher proportion of digestive serosa involvement (p<0.001), and a higher proportion of mesenteric lymph node involvement and hematogenous metastases (p=0.005 and p=0.001, respectively). When analyzing long-term outcomes, all these factors had a significant impact on overall survival. CONCLUSION: Preoperative thrombocytosis appears to be positively associated with gastrointestinal serosa involvement, mesenteric lymph node invasion, and the presence of hematogenous metastases, thus significantly influencing the long-term outcome of patients with advanced ovarian cancer.

Prognostic Factors in Intrahepatic Cholangiocarcinoma - A Systematic Review.

Introduction: intrahepatic cholangiocarcinoma (ICCA) are rare, aggressive cancers that develop in second order or smaller bile ducts. The aim of this review is to systematically review the most important prognostic factors affecting the long-term outcomes of these patients. Material and Methods: articles conducted on this issue, written in English, published between from January 2000 to December 2023 in Cochrane Library, PubMed, Embase, MedLine, Web of Science, Elsevier, Google Scholar were systematically researched and reviewed. Results: ICCA are usually late diagnosed cancers because of the asymptomatic character, and curative procedures are often not feasible, only 20 to 30% of patients being fit for surgery. With the prognostic of this aggressive malignancy being baleful, the most important risk factors but also prognosis factors seem to be represented by socioeconomic factors, morphological presentation, dimensions, number and extension of the tumor as well as resection margins. Conclusions: once these factors are widely recognized and identified in each case, the clinician will be able to find the best treatment for these patients in order to improve the long-term outcomes.

Diagnostic Challenge in Heterotopic Pancreas in the Ampulla of Vater with Obstructive Jaundice - A Case Report and Literature Review.

Heterotopic pancreas is a rare congenital abnormality. The most common location is the stomach, duodenum and proximal jejunum. Rare locations are represented by the ampulla of Vater, esophagus, ileum, Meckel diverticulum, biliary tract, mesentery and spleen. We present the case of a 49 year old patient investigated for obstructive jaundice and diagnosed with an ampullar heterotopy of pancreas parenchyma, initially considered to be a malignant tumor. A Whipple pancreatoduodenectomy was performed with good postoperative evolution, the serum levels of bilirubin being normal after the first postoperative week.

Prognostic Factors in Liver Transplant with Marginal Grafts - Review of the Literature.

Liver transplantation is the last life-saving solution for patients with end stage liver disease. The low number of available liver grafts and the increasing waiting time on transplant lists have led to the appearance of extended donation criteria and the marginal grafs, initially considered suboptimal. Allocation of grafts and identification of the most suitable "donor-recipient" pair is still under development. The fact is that the appearance of marginal grafts has expanded the donation lists and seems to have a prognosis at least comparable to the use of ideal grafts.

The Influence of Inflammatory and Nutritional Status on the Long-Term Outcomes in Advanced Stage Ovarian Cancer.

BACKGROUND: Despite improving surgical techniques and achieving more often complete debulking procedures, certain patients with advanced-stage ovarian cancer still have a very poor prognosis. The aim of the current paper is to investigate whether inflammatory and nutritional status can predict the long-term outcomes of ovarian cancer patients. METHODS: A retrospective analysis of 57 cases diagnosed with advanced-stage ovarian cancer submitted to surgery as first intent therapy was carried out. In all cases, the preoperative status was determined by calculating the CRP/albumin ratio, as well as the Glasgow score, the modified Glasgow score and the prognostic nutritional index. RESULTS: Patients presenting higher values of the CRP/albumin ratio, with a higher Glasgow score, modified Glasgow score and prognostic nutritional index (PNI), were more frequently associated with incomplete debulking surgery, a higher peritoneal carcinomatosis index and poorer overall survival (20 months versus 9 months for the CRP/albumin ratio p = 0.011, 42 versus 27 versus 12 months for the Glasgow score p = 0.042, 50 versus 19 versus 12 months for the modified Glasgow score, p = 0.001, and 54 months versus 21 months, p = 0.011 for the prognostic nutritional index). CONCLUSIONS: A strong relationship between the nutritional and inflammatory status in advanced-stage ovarian cancer seems to exist.

Risk Factors and Prognostic Factors in GBC.

Background: Gallbladder cancer (GBC) is a rare entity with a poor prognosis, usually discovered late due to nonspecific symptoms; therefore, over the last years, attention has been focused on identifying the risk factors for developing this malignancy in order to provide an early diagnosis, as well as new prognostic factors in order to modulate the long-term evolution of such cases. The aim of this review is to discuss both major risk factors and prognostic factors in GBC for a better understanding and integration of relevant and currently available information. Methods: A literature search was performed using Cochrane Library, PubMed, Google Scholar, Elsevier, and Web of Science; studies published after the year of 2000, in English, were reviewed. Results: Over time, risk factors associated with the development of GBC have been identified, which outline the profile of patients with this disease. The most important prognostic factors in GBC remain TNM staging, safety margin, and R0 status, along with perineural invasion and lymphovascular invasion. Both the technique and experience of the surgeons and a pathological examination that ensures final staging are particularly important and increase the chances of survival of the patients. Conclusions: improvements in surgical techniques and pathological analyses might provide better and more consistent guidance for medical staff in the management of patients with GBC.

Is Marginal Donor an Efficient Solution for Expanding the Donor Pool for Liver Transplant?

Once the techniques of hepatobiliopancreatic surgery improved, liver transplantation widely extended in different hospitals; therefore, the need of grafts and automatically of liver donors reported a significant increase in the last decade. In this respect, attention was focused on increasing the liver donor pool. The aim of this review is to study the benefits of using marginal grafts in liver transplantation. With the advent of multiple methods of liver preservation, the use of grafts previously considered unsuitable has become possible. Thus, extended allocation criteria have emerged. However, the allocation of these grafts must be carefully considered and analyzed in the context of both recipient and donor factors.

Recurrence and Carcinogenetic Rates of Colorectal Polyps.

AIM: to determin the recurrence rate of benign recto-colonic polyps in a 5-year interval, and compare the development rate of intrapolypoid carcinomatous lesions in polypectomized versus nonpolypectomized subjects. MATERIAL AND METHOD: a group of 77 patients diagnosed with recto-colonic polypoid lesions during the period 2014-2019 underwent colonoscopy at the time of study initiation and then annually during a five-year interval. Results: The recurrence rate of polyps increased annually from 5 to 12.5%; the highest rate was noted in the last two years. The five-year cumulative risk of neoplastic lesions was 73% in patients without polypectomy and 20% among those with endoscopic resection (p 0.05). Comparing the recurrence rate of benign lesions (60%) in patients without neoplastic findings with the recurrence rate of adenomas in patients with benign lesions (40%), a higher risk of recurrence was found in the first category, and seemed to be influenced by the personal history of pre-existing adenomatous lesions. CONCLUSION: an increased risk of colorectal polyps recurrence was reported during five year follow up; moreover, during the first three years an increased risk of malignant transformation was observed among cases in which endoscopic resection was not feasible when compared to those in which complete excision was feasible.

Prognostic Significance of Preoperative Inflammation Markers on the Long-Term Outcomes in Peritoneal Carcinomatosis from Ovarian Cancer.

Ovarian cancer remains one of the most lethal gynaecological malignancies affecting women worldwide; therefore, attention has been focused on identifying new prognostic factors which might help the clinician to select cases who could benefit most from surgery versus cases in which neoadjuvant systemic therapy followed by interval debulking surgery should be performed. The aim of the current paper is to identify whether preoperative inflammation could serve as a prognostic factor for advanced-stage ovarian cancer. Material and methods: The data of 57 patients who underwent to surgery for advanced-stage ovarian cancer between 2014 and 2020 at the Cantacuzino Clinical Hospital were retrospectively reviewed. The receiver operating characteristic curve was used to determine the optimal cut-off value of different inflammatory markers for the overall survival analysis. The analysed parameters were the preoperative level of CA125, monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR) and systemic inflammation index (SII). Results: Baseline CA125 > 780 µ/mL, NLR ≥ 2.7, MLR > 0.25, PLR > 200 and a systemic immune inflammation index (SII, defined as platelet × neutrophil-lymphocyte ratio) ≥ 84,1000 were associated with significantly worse disease-free and overall survival in a univariate analysis. In a multivariate analysis, MLR and SII were significantly associated with higher values of overall survival (p < 0.0001 and p = 0.0124); meanwhile, preoperative values of CA125, PLR and MLR were not associated with the overall survival values (p = 0.5612, p = 0.6137 and p = 0.1982, respectively). In conclusion, patients presenting higher levels of MLR and SII preoperatively are expected to have a poorer outcome even if complete debulking surgery is performed and should be instead considered candidates for neoadjuvant systemic therapy followed by interval surgery.

Hyponatremia as a Prognostic Factor in Advanced Stage Ovarian Cancer Patients.

Background: hyponatremia represents one of the most commonly encountered conditions in hospitalized patients, multiple mechanisms being cited so far, neoplastic syndromes being an important cause. The aim of the current paper is to analyse the presence and influence of the short- and long-term outcomes of hyponatremia on ovarian cancer patients submitted to surgery for advanced stage ovarian cancer. Method: 57 patients diagnosed with advanced stage ovarian cancer were submitted to surgery between 2014-2020. The patients were further classified according to the preoperative value of sodium into two groups. Results: there were 21 cases with preoperative normal values of sodium and respectively 36 cases with hyponatremia. Patients with preoperative hyponatremia associated a significantly higher rate of early postoperative complications and a significantly poorer long-term outcome. Therefore, cases with hyponatremia reported a mean disease-free survival of 10.8 months and respectively a mean overall survival of 18.5 months while cases with normal natrium levels reported a mean disease-free survival of 31.4 months and respectively a mean overall survival of 49.7 months (p=0.0001 and p 0.001). Conclusions: patients with lower preoperative values of sodium have a higher risk of developing postoperative complications and a significantly poorer outcome when compared to cases presenting normal levels of sodium preoperatively.

Platelet to Lymphocyte Ratio as a Predictive Tool for the Perioperative and Postoperative Outcomes in Advanced Stage Ovarian Cancer.

Background: platelet to lymphocyte ratio remains a significant prognostic factor in different malignancies. The aim of the current paper is to study the correlation between the preoperative values of platelet to lymphocyte ratio (PLR) and the postoperative outcomes in ovarian cancer patients. Method: we conducted a retrospective study on 57 patients submitted to cytoreductive surgery between 2014-2020. We determined the optimal cut off value of PLR for predicting survival outcomes by using the Receiver Operating Characteristic curve a value of 350 being obtained. The patients were further classified in two groups according to the PLR value. Results: there were 37 patients with PLR 350 and respectively 20 patients with PLR 350. Patients in the second group were significantly older and presented significantly higher rates of perioperative complications, a significantly higher level of circulating platelets, of CA125 and respectively a significantly lower level of circulating lymphocytes and of preoperative hemoglobin level. Meanwhile, patients in the second group reported a significantly poorer disease free and overall survival. Conclusions: ovarian cancer patients with higher preoperative levels of PLR trend to have a poorer early and long-term postoperative outcome. Therefore, in such cases more aggressive systemic therapies might be needed.

Pancreatoduodenectomy En Bloc With Superior Mesenteric Artery Resection for Borderline Resectable Pancreatic Cancer - A Case Report and Literature Review.

BACKGROUND/AIM: Pancreatic head adenocarcinoma represents the most aggressive digestive malignancy, which affects patients worldwide and is associated with poor outcomes especially due to the fact that most cases are diagnosed when local vascular invasion is already present. CASE REPORT: This is a case report of a 44-year-old patient diagnosed with a borderline resectable pancreatic head adenocarcinoma invading the superior mesenteric artery. The patient was submitted to surgery, and intraoperatively the mesenteric artery invasion was found. A pancreatoduodenectomy en bloc with superior mesenteric artery resection was performed while the continuity of the arterial structure was re-established by placing a cadaveric graft. CONCLUSION: In selected cases, extended arterial resections might be needed in order to achieve negative resection margins and therefore, to improve the chances of long-term survival.

Intrahepatic Cholangiocarcinoma - Where Do We Stand Today? Literature Review.

Intrahepatic cholangiocarcinomas represent rare and aggressive malignancies developing from the second order bile ducts to the smaller biliary branches. The aim of this narrative review is to discuss about the main diagnostic and therapeutic challenges in order to help medical and surgical oncologists to gain familiarity in regard to this subject. Articles discussing about epidemiology, histology, diagnostic, perioperative management and surgery which were published from January 2000 to September 2023 included in Cochrane Library, PubMed, Embase, MedLine, Web of Science, Elsevier, Google Scholar databases were reviewed. Articles reviewed in the current paper came to demonstrate that the main problem in such cases is related to the fact that most cases remain asymptomatic for a long period of time and therefore are diagnosed in advanced stages of the disease when curative procedures are feasible after performing extended visceral sacrifice or even worse, are no longer possible; however, the most efficient therapeutic strategy in order to improve the long term outcomes remains radical surgery. In this respect, attention was focused on improving the accuracy of the diagnostic tools and on identifying non-surgical therapeutic options which might increase the chances of achieving complete resection. Intrahepatic cholangiocarcinoma represent rare aggressive tumors with poor outcomes especially if radical surgery is not feasible.

Vascular Resections in Association With Pancreatic Resections for Locally Advanced Pancreatic Cancer.

BACKGROUND/AIM: Locally advanced pancreatic cancer has been considered for a long period of time as an unresectable lesion and therefore, all patients have been traditionally addressed to the oncological services for palliative purposes. However, due to the wide usage of newer oncological agents in association with improved surgical techniques, radical surgical procedures became feasible. The aim of this study was to present the different surgical procedures that were performed in locally advanced pancreatic cancer patients in order to achieve radical resections. PATIENTS AND METHODS: Between 2019 and 2020, six cases were submitted to pancreatic and vascular resections in Fundeni Clinical Hospital. RESULTS: In all cases, surgery with curative intent was attempted; portal vein resection was performed in five cases, whereas arterial resection was performed in three cases. Reconstruction was performed by direct re-anastomosis, by placing cadaveric or synthetic grafts. The postoperative outcomes were favourable in all cases. CONCLUSION: Vascular resections can be safely associated with pancreatic resections in cases presenting locally advanced pancreatic lesions, with acceptable morbidity rates.

Aortic Reconstruction by Cadaveric Graft After Radical Resection of Recurrent Retroperitoneal Leyomiosarcoma - A Case Report and Literature Review.

BACKGROUND/AIM: Retroperitoneal sarcomas represent very aggressive malignancies with high capacity of invading the surrounding vital structures. CASE REPORT: We present the case of a 46-year-old patient who had been initially diagnosed with a large retroperitoneal mass 18 months ago. At that moment the mass was resected en bloc with the inferior cava vein, which was reconstructed using a cadaveric graft, the histopathological studies demonstrating the presence of a leiomyosarcoma. One year later she was diagnosed with recurrent disease invading the abdominal aorta and a liver metastasis. This time the recurrence was resected en bloc with the abdominal aorta, which was reconstructed by placing a cadaveric graft; atypical liver resection was also performed. The postoperative course was uneventful. CONCLUSION: Extended vascular resections and cadaveric graft reconstructions might be needed in order to achieve a good local control of the disease in patients with retroperitoneal sarcomas.

Epidemiological trends and therapeutic challenges of malignancies in adult HIV-1-infected patients receiving combination antiretroviral therapy in a tertiary hospital from Romania: An observational retrospective study.

BACKGROUND: Malignancies have become a leading cause of morbidity and mortality in people living with HIV (PLHIV). The primary endpoint of our study was to describe the epidemiology of acquired immunodeficiency syndrome (AIDS)-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs). Epidemiological disparities, mortality predictors and survival analysis within the two groups of patients were key secondary endpoints. METHODS: We retrospectively evaluated all adult PLHIV with histopathologically proven cancers registered from 2010 to 2016 in the "Matei Balș" National Institute for Infectious Diseases, Bucharest, Romania. RESULTS: 110 eligible patients have been included in the study. The incidence of ADCs decreased from 1.6% in 2010 to 0.3% in 2016, unlike NADCs which remained fairly stable over time (0.3%). The higher CD4 count and lower HIV-RNA level at the cancer diagnosis were associated with prolonged survival in ADCs group, but not in NADCs group. The mean CD4 count was 449/mm3 to survivors and 92/mm3 to non-survivors (p=0.017). The mean level of HIV-RNA was 64,671 copies/mL to survivors and 1,760,345 copies/mL to non-survivors (p=0.002). CONCLUSIONS: A good therapeutic control of HIV infection at the diagnosis of ADCs was associated with better survival, emphasizing the key role of the effective cART in the management of HIV-associated cancers.

ART management in children perinatally infected with HIV from mothers who experience behavioural changes in Romania.

INTRODUCTION: During the recent years the rate of HIV perinatally exposed children in Romania has increased as a consequence of the expanding number of HIV-infected women. These women belong to Romania's long-terms survivors, aged between 20 and 24 years and to the group of new HIV infection cases (20-24 years), acquired through unsafe sexual contact and use of new psychoactive substance (IV). MATERIALS AND METHODS: We focused on 396 HIV perinatally exposed children born between 2008 and 2013, under surveillance in National Institute for Infectious Diseases "Prof. Dr. Matei Bals," Bucharest. Of them, 43 acquired HIV through materno-foetal transmission. Our aim was to observe the characteristics in their evolution under antiretroviral treatment and to emphasize the causes of treatment failure. Children with perinatally acquired HIV infection were followed in a retrospective case series. We assessed maternal characteristics, HIV vertical transmission prophylaxis, timing of diagnosis, immunological and virologic status and features of the evolution under combined antiretroviral therapy (cART). RESULTS: The rate of mother-to-child HIV transmission was 10.8% versus the national rate registered in 2013, namely <5%. 16% of mothers belonged to the Romanian 1990s cohort and 84% were recently infected with HIV, through unprotected sexual contact (70%) or use of new psychoactive substances (14%). 51% of mothers were diagnosed postnatally as a consequence of their reluctance to access specific health services and in 57% CD4 value was <350 cell/mm. 41% of the monitored children were diagnosed with HIV infection at birth. Their median entry CD4 value was 23% and 49% had a CD4 >25%; median entry viral load was 7 log. 16 patients (37%) had undetectable viral load after six months of treatment. In 87.5% of them the virologic suppression was achieved and maintained with one single regimen (2 NRTIs+1 NNRTI or 2 NRTIs+1 PI/r). 15 children (35%) did not achieve suppression of viral load. 19 children (44%) faced special issues related to adherence to antiretroviral treatment, due to mothers' poor adherence to a basic set of cares destined for their children. CONCLUSIONS: Prevention programmes in Romania must be designed on the basis of the new economic context and emerging psychoactive substance use. Hence, women who use drugs should benefit from a wider access to medical and social services.

TH1/TH2 cytokine levels as an indicator for disease progression in human immunodeficiency virus type 1 infection and response to antiretroviral therapy.

A recent theory stipulates that during the course of HIV infection, there is a shift in immune response from T-helper 1 to T-helper 2 responses, characterised by elevated secretions of relevant cytokines. Cytokine profiles of 15 asymptomatic (treatment naïve) and 26 symptomatic (undergoing treatment) HIV-1 patients was determined to investigate the validity of this theory. HIV-1 RNA was quantified using the COBAS TaqMan HIV-1 test, CD4 T-cell counts with the FACSCalibur flow cytometer and IL-1, IL-4, IL-6, IL-10 and IFN-gamma cytokine levels by ELISA method. The asymptomatic group had significantly higher RNA levels (p-value; 0.000006) and lower CD4 T-cell counts than the symptomatic group indicating ongoing disease progression in the absence of antiretroviral treatment and a positive response to HIV treatment by the symptomatic group. IL-1, IL-4 and IFN-gamma were undetectable in most study subjects. IL-10 and IL-6 levels was relatively lower in the asymptomatic group (mean value; 206.352 pg/ml, 10.516 pg/ml) than the symptomatic group (mean value; 417.539, 18.387 pg/ml). Lower levels of proinflammatory cytokines (IL-1, IFN-gamma) in both study groups and elevated levels of anti-inflammatory cytokine IL-10, confirms that there is a shift in immune response as HIV infection progress to AIDS. In addition, the presence of a progressive trend of anti-inflammatory cytokine, IL-10 and proinflammatory cytokine, IL-6 in 12 symptomatic patients tested 3 months after antiretroviral therapy indicates an attempt by antiretrovirals to restore immune function.
