Thyroid metastasis from rectal adenocarcinoma.

ABSTRACT: The thyroid is a rare site for metastasis, occurring in 0.1% of colorectal cases. A 46-year-old man with rectal adenocarcinoma developed an enlarging anterior neck mass and increasing carcinoembryonic antigen 2?years after curative intent treatment. Imaging showed aggressive features with invasion of the larynx, trachea and oesophagus, suspicious for anaplastic thyroid carcinoma. The patient underwent tumour debulking with neck dissection and tracheostomy. Final histopathological review revealed metastatic adenocarcinoma from a colorectal primary. Despite chemotherapy, the patient eventually succumbed to disease progression and complications of his illness. This case demonstrates that recognising rare sites of metastasis may help clinicians effectively institute earlier intervention.

Project description:BackgroundDespite the rich proximity and vascularization to the pelvic organs, metastatic lesions to the penis are incredibly uncommon. Most primary tumors are genitourinary cancers, and rectal origins are rare. Only 56 cases of metastatic penile tumors have been reported since 1870. Several palliative or curative methods, such as chemotherapy, total penectomy, and radiotherapy, have been applied to treat this condition in previous cases; however, the patient prognosis is poor. Immunotherapy is a beneficial treatment approach for multiple cancers, and recent investigations have shown that it may be beneficial for patients with advanced penile cancer.Case descriptionHerein, we report the case of a 59-year-old Chinese man who had metastatic adenocarcinoma in the penile tissue 3 years after rectal cancer resection. The patient presented with penile pain and dysuria for 6 months when he was 54 years old, and Immunohistochemical staining showed that the origin was the rectum after total penectomy. The patient received surgery, chemotherapy, radiotherapy, targeted therapy and immunotherapy positively and still survived for a further 4 years and 6 months following penectomy despite the late metastasis of rectal cancer. There are two major changes and progress after penectomy, all of which have undergone surgical treatment during continuous treatment and follow-up, the patient completed right inguinal lymphadenectomy when his right regional nodes metastasis was found 23 months after penectomy. While the patient suffered from radiation injury after 47 months after penectomy, which led to radiation necrosis and hip soft tissue infection, and the patient tended to lay prone instead of lying on the back because of the hip pain. The patient ultimately died of multiple organ failure.ConclusionsAll of the previously reported cases of penile metastasis from rectal cancer since 1870 have been reviewed. Yet, the metastatic prognosis remains poor regardless of the treatment options, except for lesions where metastasis is only limited to the penis. We found that the patient may derive more benefit from strategic therapies including surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy.

Project description:Overall declines in incidence of rectal cancer (RC) in patients older than 50 years have been mostly attributed to improvement in treatment modalities and introduction of age-based screening. Recent studies, however, have shown a rise in the incidence of RC in patients younger than 50 years. The etiology of early-onset (EO) RC is not well understood. The aim of this study is to elucidate the molecular features of (EO) RC and show its uniqueness compared to late-onset (LO) disease.Two cohorts of patients with sporadic RC were identified. Tumors and matching non-involved tissues from six (EO) RC patients (< 50 years) and six (LO) RC patients (>65 years) were obtained from Pathology archives. Deparaffinized tissues were macro-dissected from FFPE sections, RNA isolated and used for expression profiling of 770 cancer related genes representing 13 canonical pathways. Statistical analysis was performed using the Gene Expression R-script module within the nCounter software v2.6. A gene was considered to be above background if the average count for the target gene was greater than the average counts for the eight negative control genes and if the P value of the t-test was less than 0.05.When we compared rectal tumors to non-involved rectal tissues, changes in expression levels of 171 genes were statistically significant in early-onset group and 151 genes in late-onset group. Further comparative gene expression analysis between early- and late-onset rectal tumors normalized to their matching non-involved tissues revealed that changes in expression of 65 genes were unique to early-onset rectal tumors with 16 genes being up- and 49 genes down-regulated using the cutoff criteria of expression levels difference >2 fold and p-value <0.01. At the pathway level, MAPK signaling was the most deregulated pathway in early-onset rectal tumors compared to PI3K-AKT signaling pathway being the most deregulated in late-onset rectal tumors.Results of this study suggest that sporadic early-onset rectal cancer is characterized by distinct molecular events compared to late-onset disease.
