Synchronous colorectal cancer and multiple myeloma with chest wall involvement: Is this a coincidence?

Esophageal squamous cell cancer coincides with myelodysplastic syndrome/acute myelogenous leukemia: A case report and review of the literature

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors, and has high incidence and mortality rates, worldwide. Myelodysplastic syndrome (MDS), a disorder of hematopoietic stem or progenitor cells, results in marrow failure, which increases the risk of acute myeloid leukemia (AML). Few studies had reported patients who have suffered from both ESCC and MDS/AML simultaneously. To identify possible potential associations between ESCC and MDS/AML, the present case report describes a patient with both types of these tumors at the same time. Following endoscopic biopsy, the patient was revealed to have moderately differentiated SCC. MDS with excess blasts was subsequently diagnosed following bone marrow aspiration. The results of next-generation sequencing revealed that TP53 and ROS1 were both found in ESCC and MDS/AML tumors. The patient refused therapeutic intervention and died within 20 days. The current report demonstrated that hematologic malignancies presenting alongside solid tumors should be considered clinically. In addition, the report indicated that bone marrow puncture should be performed in patients with solid tumors and abnormal blood test results. Next-generation sequencing may be a useful technique for the investigation of patients with two or more neoplasms. However, more research regarding the co-existence of solid tumors with hematological malignancy are required.

The Synchronous Presence of Multiple Myelomas and Other Primary Malignant Tumors: Case Series with Literature Review

Objective

The synchronous presence of multiple myeloma (MM) and other primary malignant tumors (PMTs) were rarely reported. This study aimed to analyze several cases of MM and other PMTs in order to improve clinicians’ understanding of multiple myeloma (MM) with sMPMTs.

Methods

This study was a retrospective trial. We retrospectively analyzed six cases of the synchronous presence of MM and other PMTs and reviewed the literature to summarize the clinical features and treatment.

Results

The results showed that five cases of immunoglobulin G (IgG) and one case of kappa light chain; D-S stage: six case of stage III; ISS stage: one case of stage I, two cases of stage II, and three cases of stage III; one case each of gastric cancer (pT2N0MO, stage I), breast cancer (pT1bN0M0, stage I), lung cancer (pT1N0M0, stage I), cervical cancer (stage IB2), thyroid cancer (pT1N0M0, stage I), and diffuse large B-cell lymphoma (Ann-Arbor stage II); three of five patients underwent surgery alone, one patient underwent surgery first and then received chemotherapy at the time of pleural metastasis and the other patient only received radiotherapy; two patients were still alive, three died of progression of MM, and one died of lung cancer. The median survival time was 33.5 months (95% CI, 14.17 to 59.5months).

Conclusion

The relationship between synchronous MM and other PMTs remains unknown. Clinicians should improve their understanding of MM with sMPMTs by carrying out multidisciplinary collaboration and a patient-oriented approach to optimize treatment and prolong the survival rates of patients.
