Synchronous malignant renal mass in patient with a Lung cancer: case report and literature review

Successful first-line treatment of simultaneous multiple primary malignancies of lung adenocarcinoma and renal clear cell carcinoma: A case report

Background

Multiple Primary Malignancies (MPMs) refer to the occurrence of two or more primary malignancies in the same organ or multiple organs and tissues of the same patient simultaneously or sequentially, with an incidence rate ranging from 2-17%. According to the difference in the time of occurrence of each primary tumor, MPMs can be classified as simultaneous malignancies and heterochronic malignancies. The former refers to the occurrence of two or more malignancies one after another within 6 months, while the latter refers to the occurrence of two malignancies at an interval of more than 6 months. Currently, there is a lack of effective treatment options for MPMs both nationally and internationally.

Case presentation

The patient was a 65-year-old male smoker with a definite diagnosis of advanced lung adenocarcinoma with kirsten rat sarcoma viral oncogene (KRAS) mutation, concomitant with primary renal clear cell carcinoma (RCCC), who had a progression-free survival (PFS) for 7 months after first-line treatment with albumin-bound paclitaxel and cisplatin in combination with sintilimab.

Conclusion

In this paper, we report a case of advanced lung adenocarcinoma combined with RCCC as a concurrent double primary malignancy, which achieved a satisfactory outcome after first-line chemotherapy combined with immunotherapy, with the aim of exploring effective treatment modalities for this type of MPMs, in order to improve the survival and prognosis of the patient.

Extra-Hepatic Hepatoid Carcinomas in Female Reproductive System: Three Case-Reports with a Literature Review

PURPOSE

Hepatoid carcinoma of the ovary (HCO) and hepatoid carcinoma of the uterus (HCU) are rare malignancies that can be difficult to distinguish from other diseases such as hepatocellular carcinoma. In extremely rare cases, patients are negative for α-fetoprotein (AFP) by immunohistochemistry. Here we report 3 cases of HC of the female reproductive system, including 1 that was negative for AFP.

PATIENTS AND METHODS

Three women aged 48, 56, and 67 years were treated at Qilu Hospital of Shandong University for HCO or HCU. We describe these cases in detail, including clinical features, diagnosis, treatment, and outcome, and review similar cases reported in the literature.

RESULTS

All of our patients underwent surgery including hysterectomy and bilateral adnexectomy, and were treated with platinum-based chemotherapy. One patient died 3 months after the operation, and the other 2 are alive 22 and 63 months post surgery.

CONCLUSION

The first-choice treatment for HCO and HCU is staging surgery, which should be followed by platinum-based chemotherapy.

Primary Adenocarcinoma of Lung with Synchronous Renal Cell Carcinoma: A Case Report and Review of the Literature

Introduction: The simultaneous occurrence of two distinct tumors is rare. Distinguishing between the concomitances of two primary malignancies from metastatic disease is very important for disease management and overall survival improvement. Case Presentation: We report a case of a lung adenocarcinoma patient, who incidentally has renal cell carcinoma (RCC). This report includes clinical, radiological, and histological diagnostic challenges in an unexpected lesion and a review of the literature. Conclusions: The possibility of primary cancer should be taken into account when a lesion is detected in the lung or the kidneys. Thus, both the radiographic appearance and clinical behavior of a lesion may hold clues that can help distinguish synchronous cancers.

Primary hepatoid carcinoma of the ovary: A case report and review of the literature

INTRODUCTION

Hepatoid carcinoma of the ovary (HCO) is a rare disease that originates from the ovarian surface epithelium. It is histologically characterized as hepatocellular carcinoma (HCC) with a hepatocyte-rich granular cytoplasm.

PATIENT CONCERNS

A 65-year-old female patient was admitted with complaints of indigestion, abdominal bloating, and pain.

DIAGNOSIS

The patient showed an elevated level of serum alpha-fetoprotein (AFP) with abdominal bloating and pain. After surgery and histopathology analysis, she was finally diagnosed with HCO, Figo stage IC.

INTERVENTIONS

After cytoreductive surgery, she underwent adjuvant chemotherapy with carboplatin and paclitaxel. Although the disease was diagnosed at an early stage, it recurred 6 months after completion of adjuvant chemotherapy. Elevation of serum AFP level and removal of a mass from the lumbar vertebra confirmed the recurrence of this disease. Subsequently, the patient underwent radiation therapy and palliative chemotherapy.

OUTCOMES

She died 31 months after the diagnosis due to disease progression.

CONCLUSION

The aggressive nature of HCO was clearly observed in this case despite early diagnosis and treatment. Further studies are needed to understand the proper treatment and prognostic factors of HCO.

Synchronous Oligometastatic Non-Small Cell Lung Cancer and Isolated Renal Cell Carcinoma: A Case Report and Literature Review

A 58-year-old gentleman presenting with a progressive headache, visual disturbance, decreased appetite, and weight loss was found to have a localized clear cell carcinoma of the kidney and synchronous Stage IV non-small cell lung cancer with a solitary brain metastasis. This case illustrates the challenges in distinguishing between primary and metastatic disease in a patient with both renal cell carcinoma and lung cancer. We highlight the uncertainties in the diagnosis and management of this unique clinical scenario and the potential implications on prognosis.
