Pancreatic adenocarcinoma is a highly aggressive malignancy that usually presents at a late stage. Common sites of metastasis include the liver, lung and adjacent lymph nodes. Cervical lymph node involvement has been reported previously but there are no documented cases of submandibular lymph node metastasis in the available literature. We describe a case of pancreatic adenocarcinoma metastasis to the left submandibular lymph node with no confirmed concurrent sites of metastasis.

Delay In Treatment

Background: This is a clinicopathological study comparing the involvement of lymph nodes in various carcinomas before and during the COVID-19 period. During the pandemic the access to healthcare and timely detection and intervention of carcinomas were severely affected. This delay in treatment has led to the progression of malignancies and metastasis to lymph nodes. Methods: A retrospective study was conducted of 40 patients (20 from 2019 and 20 from 2021) with carcinomas who were treated by surgical excision of tumour combined with lymph node resection. Histopathological examination of the nodes was done to detect malignant metastasis and the average node positivity rate was calculated. Results: Lymph node metastasis was observed in 10 patients in 2019 (50%) and 16 patients in 2021 (80%). The average node positivity rate is significantly higher in 2021 than in 2019, in 2019 it is 31% and in 2021 it is 43%. Lymph node metastasis is expected to increase by 43% in 2021. Conclusion: In the Covid-19 pandemic, a significant decrease and delay of patients presenting to the OPD for neoplasms, resulting in a delay in the diagnosis and treatment of advanced-stage neoplasms that manifest as metastases in the regional lymph nodes.  Surgeons need to be vigilant and extensively explore the all draining affected lymph nodes and resect them.

Abstract Background and objectives The optimal therapeutic method for patients with superficial esophageal squamous cell carcinoma (sESCC) remains to be established. Methods Clinical data of all the patients from 2002 to 2014 who underwent curative esophagectomy and three-field lymphadenectomy for thoracic sESCC were collected based on a prospectively-maintained database. The pattern of lymph node metastasis was analyzed based on the depth of tumor invasion, tumor location and surgical fields. Results The involved lymph node region was associated to the tumor location, however, upper mediastinal and perigastric region was the most vulnerable region. The incidence of lymph node metastasis increased with the depth of tumor invasion. No lymph node involvement was found in tumors invading proper mucosa (M2), while the pattern of positive lymph nodes in tumors invading the deepest 1/3 submucosa was similar to that in advanced ESCC. Lymphatic invasion, tumor location and upper mediastinal lymph node involvement were independent predictors for cervical lymph node metastasis. For patients without lymphatic invasion, the positive predictive value of upper mediastinal lymph node metastasis for positive cervical lymph node was low (0 ~ 25%), while the negative predictive value was extremely high, wherever the tumor located (93.8 ~ 100%). Conclusions Tumors invading till proper mucosa was the best indication for endoscopic mucosa resection. Mediastinal-abdominal lymphadenectomy was essential for sESCC invading beyond proper mucosa. For those without lymphatic invasion, cervical lymphadenectomy might be avoided in case of negative upper mediastinal lymph node.

Hilar Lymph Node Metastasis

Colorectal carcinoma is the second biggest cancer responsible for mortality. Lung metastasis is the commonest, following the liver. It is not uncommon to perform pulmonary metastasectomy and identify mediastinal metastasis. Previous studies have identified incidental lymph node involvement following routine mediastinal lymph node clearance in 20–50% of cases. However, solitary intrathoracic lymph node metastasis is exceedingly rare. Even when present, it is usually metachronous. In our case, we present an exceedingly rare case whereby the intrathoracic lymph node metastasis is solitary, not accompanying pulmonary disease and with no liver metastasis. We also review the evidence for mediastinal lymphadenectomy in the literature.

There is 54.1% (13 out of 24) upstaging in T3 tumours (T2 to T3), 23% (3 out of 13) in T2 (T1 to T2).

BackgroundLymph node involvement is a major feature in tumor spread of endometrial cancer and predicts prognosis. Therefore, evaluation of lymph vessel invasion (LVI) in tumor tissue as a predictor for lymph node metastasis is of great importance. Immunostaining of D2-40 (podoplanin), a specific marker for lymphatic endothelial cells, might be able to increase the detection rate of LVI compared with conventional hematoxylin-eosin (H-E) staining. The aim of this retrospective study was to analyze the eligibility of D2-40–based LVI evaluation for the prediction of lymph node metastases and patients’ outcome.Patients and MethodsImmunohistochemical staining with D2-40 monoclonal antibodies was performed on paraffin-embedded tissue sections of 182 patients with primary endometrioid adenocarcinoma treated in 1 gynecologic cancer center. Tumors were screened for the presence of LVI. Correlations with clinicopathological features and clinical outcome were assessed.ResultsImmunostaining of D2-40 significantly increased the frequency LVI detection compared with conventional H-E staining. Lymph vessel invasion was identified by D2-40 in 53 (29.1%) of 182 tumors compared with 34 (18.3%) of 182 carcinomas by routine H-E staining (P = 0.001). D2-40 LVI was detectable in 81.0% (17/21) of nodal-positive tumors and significantly predicted lymph node metastasis (P = 0.001). Furthermore, D2-40 LVI was an independent prognostic factor for patients overall survival considering tumor stage, lymph node involvement, and tumor differentiation (P < 0.01). D2-40–negative tumors confined to the inner half of the myometrium showed an excellent outcome (5-year overall survival, 97.8%).ConclusionsD2-40–based LVI assessment improves the histopathological detection of lymphovascular invasion in endometrial cancer. Furthermore, LVI is of prognostic value and predicts lymph node metastasis. D2-40 LVI detection might help to select endometrial cancer patients who will benefit from a lymphadenectomy.

Abstract Cervical lymph node metastasis is an extremely rare event in oral verrucous carcinoma. Isolated cervical lymph node metastasis of colon cancer is also rare. This article describes a case of maxillary verrucous carcinoma accompanied by colon adenocarcinoma that metastasized to a cervical lymph node in a 69-year-old Japanese woman. During preoperative evaluation for maxillary verrucous carcinoma, enlarged cervical lymph nodes and colon cancer were suspected by positron emission tomography. Colonoscopy with biopsies confirmed primary colon adenocarcinoma. Left radical neck dissection, partial maxillectomy, and full-thickness skin graft to the mucosa of the upper lip were performed before treatment of colon adenocarcinoma. Cervical lymph nodes showed metastasis from colon adenocarcinoma, and right hemicolectomy was performed. This is the first case report of synchronous oral verrucous carcinoma and colon adenocarcinoma with cervical lymph node metastasis.
