Simultaneous ultrasonography-guided "radical but conservative" liver resection and colo-rectal resection as a safe approach to advanced colo-rectal cancer

Il cancro colorettale (CRC) rimane la prima causa di morte nei paesi occidentali.Dal 15% al 25% dei pazienti affetti da CRC presenta metastasi epatiche sincrone (CRLM) al momento della diagnosi.La resezione epatica radicale rimane l’unica terapia potenzialmente curativa in presenza di CRLM con una sopravvivenza a 5 anni compresa tra il 17% ed il 35% ed a 10 anni tra il 16% e il 23% rispettivamente. La tempistica ottimale per la resezione chirurgica in caso di presentazione sincrona di CRC è controversa.Questo studio intende dimostrare che le resezioni epatiche ecoguidate radicali ma conservative simultanee ad una resezione colorettale rappresentano una tecnica sicura ed efficace nei pazienti con CRC avanzato. 48 pazienti sono stati sottoposti ad una resezione simultanea colorettale ed epatica. L’età media +SD (range) era di 64,2+9,7 (38-84).Un solo paziente è deceduto entro 30 giorni. La mortalità post operatoria è stata complessivamente del 2,1%. Nove pazienti (18,8%) hanno sviluppato una o più complicanza ,4 (8,3%) di grado III-IV sec. Clavien-Dindo e 5 (10,4%) di grado I-II. La durata complessiva dell’intervento chirurgico simultaneo è stata di 486,6+144,0 (153-804) minuti.Questo studio conferma che le resezioni colorettali ed epatiche simultanee possono essere eseguite senza un significativo aumento della morbilità e mortalità perioperatorie, anche in pazienti sottoposti ad una resezione anteriore ultrabassa ed in quelli in cui sia indicato il clampaggio intermittente dell’ilo epatico. L’IOUS è efficace nel ridurre l’estensione della resezione epatica in pazienti sia con CRLM anche multiple e bilobari .Poichè le complicanze maggiori sono frequenti dopo resezioni epatiche maggiori simultanee, riducendo l’estensione della resezione del parenchima epatico si può avere un impatto favorevole sul decorso post operatorio.Le resezioni epatiche ecoguidate radicali ma conservative simultanee ad una resezione colorettale sono una tecnica sicura ed efficace in pazienti con carcinoma colorettale avanzato e andrebbero considerate l’opzione primaria in casi selezionatiColorectal cancer(CRC) is still one of the leading causes of cancer-related death in the Western countries. Liver metastases (CRLM) are present in nearly 15% to 25% of individuals with newly diagnosed colorectal cancer and will develop in up to 50% of patient during the course of their disease. Radical liver resection remains the only potentially curative therapy for patient with CRLM, with reported 5-and 10 year actuarial survival rates of 17% to 35% and 16% to 23%, respectively. The optimal timing for surgical resection in case of syncronous presentation of primary CRC and liver metastases has long been controversial. This study aimed to determine whether simultaneous radical but conservative IOUS-guided LR and colorectal resection (CRR) are safe and effective in patient with SCRLM. Forty-eight patients received simultaneous colorectal and liver resection. Mean+SD (range) age was 64,2+9,7 (38-84) years. One patient died within 30 p.o. days; overall postoperative mortality was 2,1%. Nine patients (18,8%) developed one or more complications, 4 (8,3%) of grade III-IV sec. Clavien-Dindo and 5 (10,4%) of grade I-II. Duration of surgery was 486,6+144,0 (153-804) minutes. Postoperative hospital stay was11,9+6,6 (6-50) days. This study confirms that simultaneous colorectal and liver resections can be performed safely without significant increase of perioperative morbidity and mortality rates, also in patients undergoing ultralow anterior resection and in those requiring intermittent hepatic pedicle clamping. IOUS guidance is effective in reducing the extension of LR in patients with SCRLM, even in those with bilobar SCRLM. Since major complications are frequent after simultaneous major LR and CRR, reducing the extent of liver parenchyma removal may have a favourable impact on postoperative course. Simultaneous radical but conservative IOUS-guided LR and CRR is a safe and effective in patient with SCRLM and could serve as primary option for selected case

Pancreatic Metastasis from Colon Carcinoma: A Case Report

Context The pancreas is an uncommon location for metastases from other primary cancers; in particular, lesions from colorectal cancer account for 1.7% of all metastases. Due to their rarity, the role of surgery in these patients is not yet clear, even though pancreatic resection is considered for isolated pancreatic metastases. The interval between colorectal surgery and pancreatic metastasis is usually short, and an interval of more than five years is exceptional. We present a patient previously operated for an adenocarcinoma of the left colon and metachronous liver metastases who developed a tumor of the pancreas during the follow-up, seven years after colon resection. To our knowledge, this is the first reported case of pancreatic resection after colon and liver resections. Case report On March 2005, an adenocarcinoma of the left colon was diagnosed in a 67-year-old male: he received left hemicolectomy (pT3N1,G2) followed by adjuvant chemotherapy. In June 2006 metachronous colorectal liver metastases were diagnosed and the patient underwent right hepatectomy. In October 2008 liver metastases recurred and he received subsegmentectomy S3. From February to October 2009 a FOLFOX based chemotherapy was performed. He was regularly monitored with CT scans of the chest and abdomen, tumor markers and colonoscopy. In January 2012 a CT scan of the abdomen showed a lesion of 26x18 mm in diameter of the tail of the pancreas, confirmed by subsequent 18FDG PET-TC. Colonoscopy was negative for recurrence of the primary disease. No other lesion was detected. A ultrasonography-guided distal splenopancreatectomy was performed. The postoperative course was characterized by the appearance of a low-flow pancreatic fistula which was treated conservatively. The patient was discharged on 16th postoperative day. Histological examination of the surgical specimen demonstrated a metastatic adeno­carcinoma of the colon. Conclusion Colorectal metastases to the pancreas are rare, but should be suspected in patients followed for colorectal malignancies. Pancreatic resection can be suggested in selected patients, but it should be deserved to experienced centers, especially in case of iterative abdominal surgery before pancreatic resection

Simultaneous curative resection of double colorectal carcinoma with synchronous bilobar liver metastases

Synchronous colorectal carcinoma (SCRC) indicates more than one primary colorectal carcinoma (CRC) discovered at the time of initial presentation, accounts for 3.1%-3.9% of CRC, and may occur either in the same or in different colorectal segments. The accurate preoperative diagnosis of SCRC is difficult and diagnostic failures may lead to inappropriate treatment and poorer prognosis. SCRC requires colorectal resections tailored to individual patients, based on the number, location, and stage of the tumours, from conventional or extended hemicolectomies to total colectomy or proctocolectomy, when established predisposing conditions exist. The overall perioperative risks of surgery for SCRC seem to be higher than for solitary CRC. Simultaneous colorectal and liver resection represents an appealing surgical strategy in selected patients with CRC and synchronous liver metastases (CRLM), even though the cumulative risks of the two procedures need to be adequately evaluated. Simultaneous resections have the noticeable advantage of avoiding a second laparotomy, give the opportunity of an earlier initiation of adjuvant therapy, and may significantly reduce the hospital costs. Because an increasing number of recent studies have shown good results, with morbidity, perioperative hospitalization, and mortality rates comparable to staged resections, simultaneous procedures can be selectively proposed even in case of complex colorectal resections, including those for SCRC and rectal cancer. However, in patients with multiple bilobar CRLM, major hepatectomies performed simultaneously with colorectal resection have been associated with significant perioperative risks. Conservative or parenchymal-sparing hepatectomies reduce the extent of hepatectomy while preserving oncological radicality, and may represent the best option for selected patients with multiple CRLM involving both liver lobes. Parenchymal-sparing liver resection, instead of major or two-stage hepatectomy for bilobar disease, seemingly reduces the overall operative risk of candidates to simultaneous colorectal and liver resection, and may represent the most appropriate surgical strategy whenever possible, also for patients with advanced SCRC and multiple bilobar liver metastases

Radiomic Analysis of Intrahepatic Cholangiocarcinoma: Non-Invasive Prediction of Pathology Data: A Multicenter Study to Develop a Clinical-Radiomic Model

: Standard imaging cannot assess the pathology details of intrahepatic cholangiocarcinoma (ICC). We investigated whether CT-based radiomics may improve the prediction of tumor characteristics. All consecutive patients undergoing liver resection for ICC (2009-2019) in six high-volume centers were evaluated for inclusion. On the preoperative CT, we segmented the ICC (Tumor-VOI, i.e., volume-of-interest) and a 5-mm parenchyma rim around the tumor (Margin-VOI). We considered two types of pathology data: tumor grading (G) and microvascular invasion (MVI). The predictive models were internally validated. Overall, 244 patients were analyzed: 82 (34%) had G3 tumors and 139 (57%) had MVI. For G3 prediction, the clinical model had an AUC = 0.69 and an Accuracy = 0.68 at internal cross-validation. The addition of radiomic features extracted from the portal phase of CT improved the model performance (Clinical data+Tumor-VOI: AUC = 0.73/Accuracy = 0.72; +Tumor-/Margin-VOI: AUC = 0.77/Accuracy = 0.77). Also for MVI prediction, the addition of portal phase radiomics improved the model performance (Clinical data: AUC = 0.75/Accuracy = 0.70; +Tumor-VOI: AUC = 0.82/Accuracy = 0.73; +Tumor-/Margin-VOI: AUC = 0.82/Accuracy = 0.75). The permutation tests confirmed that a combined clinical-radiomic model outperforms a purely clinical one (p < 0.05). The addition of the textural features extracted from the arterial phase had no impact. In conclusion, the radiomic features of the tumor and peritumoral tissue extracted from the portal phase of preoperative CT improve the prediction of ICC grading and MVI

GOSAFE - Geriatric Oncology Surgical Assessment and Functional rEcovery after Surgery:early analysis on 977 patients

Objective: Older patients with cancer value functional outcomes as much as survival, but surgical studies lack functional recovery (FR) data. The value of a standardized frailty assessment has been confirmed, yet it's infrequently utilized due to time restrictions into everyday practice. The multicenter GOSAFE study was designed to (1) evaluate the trajectory of patients' quality of life (QoL) after cancer surgery (2) assess baseline frailty indicators in unselected patients (3) clarify the most relevant tools in predicting FR and clinical outcomes. This is a report of the study design and baseline patient evaluations. Materials & Methods: GOSAFE prospectively collected a baseline multidimensional evaluation before major elective surgery in patients (≥70 years) from 26 international units. Short−/mid−/long-term surgical outcomes were recorded with QoL and FR data. Results: 1003 patients were enrolled in a 26-month span. Complete baseline data were available for 977(97.4%). Median age was 78 years (range 70–94); 52.8% males. 968(99%) lived at home, 51.6% without caregiver. 54.4% had ≥ 3 medications, 5.9% none. Patients were dependent (ADL 20 s (5.2%) or ASAIII-IV (48.8%). Major comorbidities (CACI > 6) were detected in 36%; 20.9% of patients had cognitive impairment according to Mini-Cog. Conclusion: The GOSAFE showed that frailty is frequent in older patients undergoing cancer surgery. QoL and FR, for the first time, are going to be primary outcomes of a real-life observational study. The crucial role of frailty assessment is going to be addressed in the ability to predict postoperative outcomes and to correlate with QoL and FR

Predicting Functional Recovery and Quality of Life in Older Patients Undergoing Colorectal Cancer Surgery: Real-World Data From the International GOSAFE Study

PURPOSE The GOSAFE study evaluates risk factors for failing to achieve good quality of life (QoL) and functional recovery (FR) in older patients undergoing surgery for colon and rectal cancer.METHODS Patients age 70 years and older undergoing major elective colorectal surgery were prospectively enrolled. Frailty assessment was performed and outcomes, including QoL (EQ-5D-3L) recorded (3/6 months postoperatively). Postoperative FR was defined as a combination of Activity of Daily Living >= 5 + Timed Up & Go test <20 seconds + MiniCog >2.RESULTS Prospective complete data were available for 625/646 consecutive patients (96.9%; 435 colon and 190 rectal cancer), 52.6% men, and median age was 79.0 years (IQR, 74.6-82.9 years). Surgery was minimally invasive in 73% of patients (321/435 colon; 135/190 rectum). At 3-6 months, 68.9%-70.3% patients experienced equal/better QoL (72.8%-72.9% colon, 60.1%-63.9% rectal cancer). At logistic regression analysis, preoperative Flemish Triage Risk Screening Tool >= 2 (3-month odds ratio [OR], 1.68; 95% CI, 1.04 to 2.73; P = .034, 6-month OR, 1.71; 95% CI, 1.06 to 2.75; P = .027) and postoperative complications (3-month OR, 2.03; 95% CI, 1.20 to 3.42; P = .008, 6-month OR, 2.56; 95% CI, 1.15 to 5.68; P = .02) are associated with decreased QoL after colectomy. Eastern Collaborative Oncology Group performance status (ECOG PS) >= 2 is a strong predictor of postoperative QoL decline in the rectal cancer subgroup (OR, 3.81; 95% CI, 1.45 to 9.92; P = .006). FR was reported by 254/323 (78.6%) patients with colon and 94/133 (70.6%) with rectal cancer. Charlson Age Comorbidity Index >= 7 (OR, 2.59; 95% CI, 1.26 to 5.32; P = .009), ECOG >= 2 (OR, 3.12; 95% CI, 1.36 to 7.20; P = .007 colon; OR, 4.61; 95% CI, 1.45 to 14.63; P = .009 rectal surgery), severe complications (OR, 17.33; 95% CI, 7.30 to 40.8; P < .001), fTRST >= 2 (OR, 2.71; 95% CI, 1.40 to 5.25; P = .003), and palliative surgery (OR, 4.11; 95% CI, 1.29 to 13.07; P = .017) are risk factors for not achieving FR.CONCLUSION The majority of older patients experience good QoL and stay independent after colorectal cancer surgery. Predictors for failing to achieve these essential outcomes are now defined to guide patients' and families' preoperative counseling

Quality of life in older adults after major cancer surgery: the GOSAFE international study

Abstract Background Accurate quality of life (QoL) data and functional results after cancer surgery are lacking for older patients. The international, multicenter Geriatric Oncology Surgical Assessment and Functional rEcovery after Surgery (GOSAFE) Study compares QoL before and after surgery and identifies predictors of decline in QoL. Methods GOSAFE prospectively collected data before and after major elective cancer surgery on older adults (≥70 years). Frailty assessment was performed and postoperative outcomes recorded (30, 90, and 180 days postoperatively) together with QoL data by means of the three-level version of the EuroQol five-dimensional questionnaire (EQ-5D-3L), including 2 components: an index (range = 0-1) generated by 5 domains (mobility, self-care, ability to perform the usual activities, pain or discomfort, anxiety or depression) and a visual analog scale. Results Data from 26 centers were collected (February 2017-March 2019). Complete data were available for 942/1005 consecutive patients (94.0%): 492 male (52.2%), median age 78 years (range = 70-95 years), and primary tumor was colorectal in 67.8%. A total 61.2% of all surgeries were via a minimally invasive approach. The 30-, 90-, and 180-day mortality was 3.7%, 6.3%, and 9%, respectively. At 30 and 180 days, postoperative morbidity was 39.2% and 52.4%, respectively, and Clavien-Dindo III-IV complications were 13.5% and 18.7%, respectively. The mean EQ-5D-3L index was similar before vs 3 months but improved at 6 months (0.79 vs 0.82; P < .001). Domains showing improvement were pain and anxiety or depression. A Flemish Triage Risk Screening Tool score greater than or equal to 2 (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.13 to 2.21, P = .007), palliative surgery (OR = 2.14, 95% CI = 1.01 to 4.52, P = .046), postoperative complications (OR = 1.95, 95% CI = 1.19 to 3.18, P = .007) correlated with worsening QoL. Conclusions GOSAFE shows that older adults’ preoperative QoL is preserved 3 months after cancer surgery, independent of their age. Frailty screening tools, patient-reported outcomes, and goals-of-care discussions can guide decisions to pursue surgery and direct patients’ expectations
