Prognostic value of specific KRAS mutations in patients with colorectal peritoneal metastases. ESMO Open 2024; 9:102976. [PMID: 38613907 PMCID: PMC11033065 DOI: 10.1016/j.esmoop.2024.102976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 02/17/2024] [Accepted: 02/29/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND There is little evidence on KRAS mutational profiles in colorectal cancer (CRC) peritoneal metastases (PM). This study aims to determine the prevalence of specific KRAS mutations and their prognostic value in a homogeneous cohort of patients with isolated CRC PM treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. MATERIALS AND METHODS Data were collected from 13 Italian centers, gathered in a collaborative group of the Italian Society of Surgical Oncology. KRAS mutation subtypes have been correlated with clinical and pathological characteristics and survival [overall survival (OS), local (peritoneal) disease-free survival (LDFS) and disease-free survival (DFS)]. RESULTS KRAS mutations occurred in 172 patients (47.5%) out of the 362 analyzed. Two different prognostic groups of KRAS mutation subtypes were identified: KRASMUT1 (G12R, G13A, G13C, G13V, Q61H, K117N, A146V), median OS > 120 months and KRASMUT2 (G12A, G12C, G12D, G12S, G12V, G13D, A59E, A59V, A146T), OS: 31.2 months. KRASMUT2 mutations mainly occurred in the P-loop region (P < 0.001) with decreased guanosine triphosphate (GTP) hydrolysis activity (P < 0.001) and were more frequently related to size (P < 0.001) and polarity change (P < 0.001) of the substituted amino acid (AA). When KRASMUT1 and KRASMUT2 were combined with other known prognostic factors (peritoneal cancer index, completeness of cytoreduction score, grading, signet ring cell, N status) in multivariate analysis, KRASMUT1 showed a similar survival rate to KRASWT patients, whereas KRASMUT2 was independently associated with poorer prognosis (hazard ratios: OS 2.1, P < 0.001; DFS 1.9, P < 0.001; LDFS 2.5, P < 0.0001). CONCLUSIONS In patients with CRC PM, different KRAS mutation subgroups can be determined according to specific codon substitution, with some mutations (KRASMUT1) that could have a similar prognosis to wild-type patients. These findings should be further investigated in larger series.

Abstract
Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10^{-28} cm^{3} s^{-1} at 1 TeV and ⟨σv⟩≲1×10^{-25} cm^{3} s^{-1} at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

Abstract
On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models. Based on a set of assumptions on the possible intrinsic spectral and temporal evolution, we obtain competitive lower limits on the quadratic leading order of speed of light modification.

Abstract
INTRODUCTION Transverse colon cancer (TCC) is poorly studied, and TCC cases are often excluded from large prospective randomized trials because of their complexity and their potentially high complication rate. The best surgical approach for TCC has yet to be established. The aim of this large retrospective multicenter Italian series is to investigate the advantages and disadvantages of both hemicolectomy and transverse colectomy in order to identify the best surgical approach. MATERIALS AND METHODS This was a retrospective cohort study of patients with mid-transverse colon cancer treated with a segmental colon resection or an extended hemicolectomy (right or left) between 2006 and 2016 in 28 high-volume (more than 70 procedures/year) Italian referral centers for colorectal surgery. RESULTS The study included 1529 patients, 388 of whom underwent a segmental resection while 1141 underwent an extended resection. A higher number of complications has been reported in the segmental group than in the extended group (30.1% versus 23.6%; p 0.010). In 42 cases the main complication was the anastomotic leak (4.4% versus 2.2%; p 0.020). Recovery outcomes also showed statistical differences: time to first flatus (p 0.014), time to first mobilization (p 0.040), and overall hospital stay (p < 0.001) were significantly shorter in the extended group. Even if overall survival were similar between the groups (95.1% versus 97%; p 0.384), 3-year disease-free survival worsened after segmental resection (78.1% versus 86.2%; p 0.001). CONCLUSIONS According to our results, an extended right colon resection for TCC seems to be surgically safer and more oncologically valid.

Abstract
BACKGROUND The objective of this study was to compare the 7th and the 8th edition of American Joint Committee on Cancer staging system (AJCC TNM) in terms of better stratification in our gastric cancer resected patients. METHODS AND MATERIALS A retrospective analysis of a single western center series was made. Patients who underwent surgery from January 2004 to December 2016 were enrolled in the study. We compared survival rates across patients classified according to the 7th and the 8th AJCC TNM staging system. RESULTS Among 295 patients we observed 9.8% stage migration according the 8th edition. Of these 2.1% and 7.9% of patients showed respectively a higher and a lower stage. 5 years Overall Survival (5Y-OS) according to the 8th edition for stage IIIB and IIIC were 32% versus 9% showing a better stratification compared to the 7th edition in which 5Y-OS were respectively 26% versus 22%. CONCLUSION Restaging system seems to improve survival rate discrimination in particular comparing stage IIIB and stage IIIC; whereas in stage IIIA this is not so clear. More studies are necessary to confirm these data.

Abstract
Numerical simulations are foreseen to provide a tremendous increase in gas-turbine burners efficiency in the near future. Modern developments in numerical schemes, turbulence models and the consistent increase of computing power allow Large Eddy Simulation (LES) to be applied to real cold flow industrial applications. However, the detailed simulation of the gas-turbine combustion process remains still prohibited because of its enormous computational cost. Several numerical models have been developed in order to reduce the costs of flame simulations for engineering applications. In this paper, the Flamelet-Generated Manifold (FGM) chemistry reduction technique is implemented and progressively extended for the inclusion of all the combustion features that are typically observed in stationary gas-turbine combustion. These consist of stratification effects, heat loss and turbulence. Three control variables are included for the chemistry representation: the reaction evolution is described by the reaction progress variable, the heat loss is described by the enthalpy and the stratification effect is expressed by the mixture fraction. The interaction between chemistry and turbulence is considered through a presumed beta-shaped probability density function (PDF) approach, which is considered for progress variable and mixture fraction, finally attaining a 5-D manifold. The application of FGM in combination with heat loss, fuel stratification and turbulence has never been studied in literature. To this aim, a highly turbulent and swirling flame in a gas turbine combustor is computed by means of the present 5-D FGM implementation coupled to an LES turbulence model, and the results are compared with experimental data. In general, the model gives a rather good agreement with experimental data. It is shown that the inclusion of heat loss strongly enhances the temperature predictions in the whole burner and leads to greatly improved NO predictions. The use of FGM as a combustion model shows that combustion features at gas turbine conditions can be satisfactorily reproduced with a reasonable computational effort. The implemented combustion model retains most of the physical accuracy of a detailed simulation while drastically reducing its computational time, paving the way for new developments of alternative fuel usage in a cleaner and more efficient combustion.

Abstract
BACKGROUND Gastrectomy with extended lymphadenectomy is considered the gold standard treatment for advanced gastric cancer, with no age- or comorbidity-related limitations. We evaluated the safety and efficacy of curative gastrectomy with extended nodal dissection, verifying survival in elderly and highly co-morbid patients. METHODS In a retrospective multicenter study, we examined 1322 non-metastatic gastric-cancer patients that underwent curative gastrectomy with D2 versus D1 lymphadenectomy from January 2000 to December 2009. Postoperative complications, overall survival (OS), and disease-specific survival (DSS) according to age and the Charlson Comorbidity Score were analyzed in relation to the extent of lymphadenectomy. RESULTS Postoperative morbidity was 30.4%. Complications were more frequent in highly co-morbid elderly patients, and, although general morbidity rates after D2 and D1 lymphadenectomy were similar (29.9% and 33.2%, respectively), they increased following D2 in highly co-morbid elderly patients (39.6%). D2-lymphadenectomy significantly improved 5-year OS and DSS (48.0% vs. 37.6% in D1, p < 0.001 and 72.6% vs. 58.1% in D1, p < 0.001, respectively) in all patients. In elderly patients, this benefit was present only in 5-year DSS. D2 nodal dissection induced better 5-year OS and DSS rates in elderly patients with positive nodes (29.7% vs. 21.2% in D1, p = 0.008 and 47.5% vs. 30.6% in D1, p = 0.001, respectively), although it was present only in DSS when highly co-morbid elderly patients were considered. CONCLUSION Extended lymphadenectomy confirmed better survival rates in gastric cancer patients. Due to high postoperative complication rate and no significant improvement of the OS, D1 lymphadenectomy should be considered in elderly and/or highly co-morbid gastric cancer patients.

Abstract
PURPOSE To investigate clinical factors influencing the prognosis of patients submitted to hepatectomy for metastases from gastric cancer and their clinical role. METHODS Retrospective multi-center chart review. We evaluated how survival from surgery was influenced by patient-related, gastric cancer-related, metastasis-related and treatment-related candidate prognostic factors. RESULTS One hundred and five patients submitted to hepatectomy for metastases from gastric cancer, in the synchronous and metachronous setting of the disease. In 89 cases a R0 resection was achieved, while in 16 a R+ hepatic resection was performed. Adjuvant chemotherapy was administered to 29 patients. Surgical mortality was 1% and morbidity 13.3%. Median disease-free survival was 10 months, median overall survival was 14.6 months. Overall 1, 3, and 5-year survival rates were 58.2%, 20.3%, and 13.1%, respectively. Survival was influenced independently by the factor T of the gastric primary (p < 0.001), by the curativity of surgical procedure (p = 0.001), by the timing of hepatic involvement (p < 0.001) and by adjuvant chemotherapy (p < 0.001). T4 gastric cancer, R+ resection, synchronous metastases, and abstention from adjuvant chemotherapy were associated with a worse prognosis; T4 gastric cancer and R+ resections displayed a cumulative effect (p < 0.001). CONCLUSIONS Our data show that R0 resection must be pursued whenever possible. Furthermore, in the synchronous setting, the coexistence of T4 gastric primaries and R+ resections suggests prudence and probably abstention from hepatectomy. Finally, a multimodal treatment associating surgery and chemotherapy offers the best survival results.

Abstract
Background The aim of our study is to analyze survival, treatment-related morbidity, and safety in our experience of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Methods Sixty-four patients were treated. Survival curves were calculated according to the Kaplan-Meier method. Univariate and multivariate analyses were done, and Cox’s proportional hazard model was used to identify significant factors. Results Global 5-year overall survival was 55 %. Overall survival was also evaluated according to neutrophils to lymphocytes ratio and neutrophils to platelets ratio. Overall survival according to pre-operative serum albumin level shows a difference in the two groups (P < 0.05). We observed minor or no adverse events in 53 cases (89.8 %), while 3 patients (5.1 %) showed a grade III–IV complication and 3 post-operative deaths (5.1 %). Post-operative complication also influenced overall survival; patients in whom a minor complication occurred had a 3-year overall survival (OS) of 62 % vs. a 3-year OS of 28 % in patients who underwent a major complication (P < 0.1). Conclusions Hyperthermic intraperitoneal chemotherapy (HIPEC) could be a valid and feasible option for selected patients affected by gastrointestinal malignancies’ peritoneal carcinomatosis. Pre-operative parameters could be evaluated to choose patient who could benefit from cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Abstract
AIM The effectiveness of Doppler guided transanal haemorrhoidal dearterialization (THD) for arresting persistent haemorrhoidal bleeding in patients admitted as an emergency was studied. METHOD Eleven patients with severe anal bleeding underwent emergency THD as definitive treatment for haemorrhoids. In the majority of patients antiplatelet or anticoagulant therapy was ongoing and severe anaemia was present in six patients. RESULTS The mean operative time was 39.7 min. Six to nine feeding arteries were ligated. Intra-operative blood loss was nil. Bleeding was well controlled in all patients. No blood transfusion was required. Mean pain score per verbal numeric scale was 3.6 and 1.4 on day 1 and day 3 respectively. The mean time to resumption of normal activities was 8 days. No major complications were experienced. Six months follow-up demonstrated good control of haemorrhoidal disease. CONCLUSION THD is effective in controlling acute haemorrhoidal bleeding with a low incidence of postoperative complications.

Abstract
Extrapleural Solitary Fibrous Tumors (SFT), in particular small bowel mesentery SFTs, are extremely rare neoplasms. We describe the case of a young male hospitalized for unspecific abdominal symptoms and evidence of a well-circumscribed mass arising from the small bowel mesentery. Histopathological and immunohistochemical analysis on the surgical specimen confirmed the diagnosis of SFT. A Pubmed search revealed only another case of small bowel mesentery SFT, confirming the extremely rarity of this tumor.

Abstract
OBJECTIVE Lung cancer represents the leading cause of tumor death in the world with 50% of patients presenting metastatic disease at the time of diagnosis. Gastrointestinal (GI) lung cancer metastasis were thought to be extremely rare, but a much higher incidence has been noted in several autoptic reports. Clinical relevance of GI metastasis is low, but can increase with the higher number of newly diagnosed patients and with the efficacy of systemic chemotherapy in advanced stages. Prognosis of complicated GI lung cancer metastasis seems to be worse than the natural course of the disease and acute bleeding or perforation of metastatic site can be accelerated by chemotherapy. CASE REPORT We describe the clinical case of a patient presenting with acute abdomen due to small bowel perforation from GI lung cancer metastasis. A review of the most recent published literature on GI lung cancer metastasis was performed. DISCUSSION GI metastasis from lung cancer may occur within the clinical course of the disease and require surgical treatment followed by a poor outcome. Percentage of lung cancer patients with GI metastasis can reach level of 14%. Large cells carcinomas causing kidney and adrenal metastasis are more likely associated with GI localization of the disease. CONCLUSIONS Complications of GI metastases, although rare, must be considered as possible cause of acute abdomen in patients with lung cancer. Identification of clinical indicators of GI metastasis may help in the therapeutic strategy.

Abstract
A case of long-term survivor 50-year-old man treated for advanced gastric cancer with two liver metastases is described. Patient underwent a total gastrectomy with D2 lymphadenectomy and atipic liver resection. After surgery, chemotherapy with PELF achieved a complete clinical response; six month from the fourth cycle, Ca19.9 levels slowly increased until 185 U/mL and a retro-peritoneal lymphadenopathy was detected by US. Three different chemotherapeutic combinations (FOLFOX, FOLFIRI, FOLFOX4) was administrated but two new liver recurrences spread out. From November 2007 until now, patient received 8 CDF cycles and he obtained a complete clinical response supported by persistent negativity of TC-PET scans. The radiological investigations performed after last admission in our Department for jaundice, revealed multiple liver lesions with Ca 19.9 levels of 6.766 U/mL. The patient required placement of metallic biliary endoprosthesis. He is still alive 41 month after primary surgery. We consider this case a successful example of survival increasing by integrated surgery-chemotherapy treatment but also an expression of the failure of current available therapy in the definitive cure for gastric cancer. Metastatic gastric cancer should be considered a disease treatable but not curable.

Abstract
AIM Gastric Cancer (GC) is a poor prognosis neoplasm and it is often diagnosed at advanced stage. Neoadjuvant Chemotherapy (NAC) may increase the possibility of complete surgical resection and improve Overall Survival (OS). PATIENTS AND METHODS Since November 2006, six patients with gastric adenocarcinoma, diagnosed by endoscopy, endoscopic ultrasonography and total body 18FDG-PET-CT, were enrolled in a program of peri-operative chemotherapy, according to the following inclusion criteria: cT2N+M0 or cT3-4NxM0, age < 75 years, Karnofsky Performance Status > 60%, absence of hepatic, renal and bone marrow failures. The patients undergo three cycles of pre-operative and post-operative chemotherapy based on Epirubicine, Cisplatin, and 5-Fluorouracil (ECF) as MAGIC Trial proposed. Fifteen days after the end of pre-operative chemotherapy the patient undergoes endoscopic ultrasonography and total body 18FDG-PET-CT to evaluate the tumor response to treatment, and then he is addressed to surgery. Thirty days after surgery he starts the post-operative chemotherapy. RESULTS All patients completed the pre-operative chemotherapy. Five patients underwent D2 subtotal gastrectomy and only one patient D1 total gastrectomy. No peri- and post-operative mortality and morbidity were observed. One month after surgery all patients started chemotherapy. During post-operative chemotherapy two patients developed subclavian vein thrombosis, one patient developed renal failure. CONCLUSIONS Although surgical resection remains the key component in the treatment of GC, it is clear that improved outcome will depend on a multidisciplinary treatment. NAC is associated with appreciable toxicity and it may improve the OS, allowing the downstaging of the primary tumor and increasing its resecability, as shown by MAGIC trial.

Abstract
Malignant ascites is a pathological condition, due to several abdominal and extra-abdominal neoplasms, representing a difficult challenge in treatment. Different medical and surgical options have been proposed, but none of them have shown efficacy, leading only to partial and temporary relief of symptoms. Laparoscopic intraperitoneal chemotherapy may be a valid therapeutic option in patients in whom medical therapies have failed and peritoneovenous shunting is contraindicated. A 49-years old woman with malignant ascites, secondary to peritoneal localization of right pleural mesothelioma, underwent, after failure of medical therapy, laparoscopic intraperitoneal chemotherapy (with Cisplatin 25 mg/m2/L and Doxorubicin 7 mg/m2/L). An important and lasting reduction of ascites and abdominal symptoms was documented till the exitus, due to pulmonary embolism after 11 months. Laparoscopic intraperitoneal chemotherapy may be a good therapeutic option to palliative malignant ascites in patient not eligible for a radical cytoreductive treatment, but further investigations are needed to standardized dosage and perfusion procedure.
