Mean Corpuscular Volume as a Prognostic Factor for Patients With Habitual Alcohol or Tobacco Use After Esophagectomy

BackgroundThe goal of this study was to investigate the impact of mean corpuscular volume (MCV) in patients with esophageal squamous cell carcinoma (ESCC) who underwent surgical resection.MethodsA total of 615 patients with ESCC who underwent esophagectomy were analyzed. Patients were divided into two groups according to the standard MCV: the high MCV group (>100 fl) and the low MCV group (≤100 fl). Survival analyses were performed to calculate overall survival (OS) and cancer-specific survival (CSS) and investigate the independent prognostic factors.ResultsFifty-one patients (8.3%) were in the high MCV group, and the other 564 patients (91.7%) were defined as the low MCV group. MCV was significantly correlated with sex, habitual alcohol or tobacco use, tumor length, body mass index, and multiple primary malignancies (P < 0.05). Elevated MCV was significantly correlated with poor survival in univariate and multivariate analyses. However, in subgroup analyses, MCV was found to be correlated with survival only in patients with alcohol or tobacco consumption and not in patients without alcohol or tobacco consumption.ConclusionsPretreatment MCV was correlated with survival in ESCC patients after esophagectomy. However, its prognostic value might only exist in patients with alcohol or tobacco consumption.

111 CLINICAL IMPORTANCE OF MEAN CORPUSCULAR VOLUME AS A PROGNOSTIC MARKER AFTER ESOPHAGECTOMY FOR ESOPHAGEAL CANCER

High MCV is suggested to be relevant to the incidence and prognosis of several malignancies. However, few studies investigating the correlation between MCV and survival outcome of esophageal cancer have been conducted. Methods This study included 570 patients with esophageal cancer who underwent radical esophagectomy between April 2005 and December 2017. Patients were divided into two groups according to the standard value of pretreatment MCV: normal (83–99 fL) and high (>99 fL) groups. Clinical backgrounds, short-term outcomes, and prognostic outcomes post-esophagectomy were retrospectively compared between the groups. Results Of all patients, 410 (71.9%) had normal MCV, and 160 (28.1%) had high MCV. High MCV was significantly associated with lower body mass index, higher frequency of habitual alcohol and tobacco use, and higher incidence of multiple primary malignancies other than esophageal cancer. High MCV also correlated with higher incidence of postoperative morbidity of the Clavien–Dindo classification ≥II and pulmonary morbidity. Overall survival was significantly worse in patients with high MCV. Multivariate analysis suggested that high MCV was an independent risk factor for worse survival outcome (hazard ratio, 1.54; 95% confidence interval, 1.098–2.151; p = 0.012). Conclusion Patients with high MCV have various disadvantages in clinical background that can adversely affect both short-term and long-term outcomes after esophagectomy. MCV can become a predictive marker to estimate survival outcome after esophagectomy for esophageal cancer.

Prognostic Impact and Clinicopathological Features of Multiple Colorectal Cancers and Extracolorectal Malignancies: A Nationwide Retrospective Study

<b><i>Introduction:</i></b> Multiple primary malignancies (MPMs) are likely to develop in patients with colorectal cancer (CRC); however, their prognoses are unclear. This study aims to investigate the prognostic impacts and clinicopathological features of multiple CRCs and extracolorectal malignancies (EMs) with CRC. <b><i>Methods:</i></b> We retrospectively evaluated a total of 22,628 patients with stage I–III CRC who underwent curative resection at 24 referral institutes in Japan between January 2004 and December 2012. MPMs were classified as synchronous CRCs (SCRCs), metachronous CRCs, synchronous EMs (SEMs), and metachronous EMs. <b><i>Results:</i></b> The presence of SCRCs (odds ratio 1.54, <i>p</i> &#x3c; 0.001) was independently associated with SEMs in the multivariate analyses. SEMs were the strongest poor prognostic factor for OS (hazard ratio [HR] 2.21, <i>p</i> &#x3c; 0.001) and RFS (HR 1.69, <i>p</i> &#x3c; 0.001) compared with age, sex, and primary T and N factors. The incidence of stomach cancer was the highest in EMs, followed by lung, breast, and prostate cancers. Multiple CRCs were evenly distributed throughout the right-side colon to the rectum. <b><i>Discussion/Conclusion:</i></b> SEMs were a strong poor prognostic factor for patients with stage I–III CRC. Patients with CRC, particularly those with SCRCs, should be surveyed for SEMs, especially for stomach and lung cancers.

Multiple primary malignancies: synchronous lymphoma, pancreatic neuroendocrine tumour and colorectal cancer

A 67-year-old woman underwent a medical check-up by her general practitioner after complaining of atypical pain in the shoulder girdle. Due to the important inflammatory syndrome noticed on blood testing, a polymyalgia rheumatica was suspected and she was started on corticosteroid treatment with good clinical response, but no impact on inflammation. She underwent extensive imaging with a thoraco-abdominal CT scanner that demonstrated a pancreatic mass, then later a PET-CT showed 3 different hyperactive lesions. Biopsies then revealed simultaneous diffuse large B-cell lymphoma (DLBCL), colorectal adenocarcinoma and pancreatic neuroendocrine tumour. She benefited from low rectal endoscopic excision of the colorectal tumour, R-CHOP chemotherapy for DLBCL and laparoscopic left pancreatectomy. Successful treatment required a good multidisciplinary collaboration between the different specialists. The patient made a good recovery and achieved complete remission at 1 year. This an unusual presentation of multiple primary malignancies.
