Cancer in Moroccan elderly: the first multicenter transverse study exploring the sociodemographic characteristics, clinical profile and quality of life of elderly Moroccan cancer patients

Background

Moroccan incidence of cancer is increasing with the lengthening of life expectancy. Data regarding elderly Moroccan cancer patients are lacking. In the context of our project aiming to develop an adapted version of the Comprehensive Geriatric Assessment CGA to the Moroccan population, we launched the first Moroccan multicenter transverse study to explore the characteristics of elderly Moroccan cancer patients.

Methods

The study was conducted in nine Moroccan medical oncology departments. Patients were enrolled over 4 months. Inclusion criteria were patients aged 65 years or over with verified solid cancer. The questionnaire included four sections: socio-demographic and economic data, clinical data, vulnerability and EORTC-QLQ C30. We explored the entire included population. Then, we compared the results according to age (65–70 years old and ≥ 71 years old) and sex. We also explored the correlation between G8 scores and the ability to practice religion as an indicator of fitness level.

Results

In total, 164 patients were enrolled. The mean age was 73.18 ± 6.01 years. The majority of patients were married, lived with their children and received their financial income from them. Fifteen percent of families asked to hide the diagnosis from the patient. Breast (23%), colorectal (15.9%) and lung (14%) cancers were the most frequent, and 83.5% had an abnormal G8. The majority of the patients were independent for basic daily activities. Female patients had poorer social and economic conditions. Abnormal G8 was correlated with religious practice and quality of life scores.

Conclusion

This is the first multicenter prospective study designed to collect data on the lifestyle and clinical profiles of elderly Moroccan cancer patients as an Arab and Muslim population. Our study shows that it is a well-cared-for population with strong social ties. However, there is deep economic vulnerability, especially among women, requiring urgent care. Religious practice is an important daily activity for our elderly patients and should be included in the Moroccan CGA.

Toxic epidermal necrolysis in a female with metastatic breast cancer treated with vinorelbine

Vinorelbine is an anticancer agent with high clinical efficacy for the treatment of metastatic breast cancer. Toxic epidermal necrolysis is a rare but serious cutaneous adverse reaction associated with drug therapy. We hereby present a case report of a patient with metastatic breast cancer, treated with vinorelbine, who developed toxic epidermal necrolysis. To the best of our knowledge, ours is the second case report describing this exceptional dermatologic emergency associated with vinorelbine. In June 2014, a 33-year-old female was treated for localized breast cancer. In December 2016, a brain magnetic resonance imaging revealed cerebral and cerebellar recurrence of the breast cancer. Whole brain radiation therapy was administered and treatment with vinorelbine was subsequently initiated. On day 3 of the first cycle of chemotherapy, she presented a general malaise and an itchy rash with conjunctivitis, oral ulcers and diffuse alopecia. The clinical diagnosis was toxic epidermal necrolysis due to vinorelbine. The patient was transferred to the burn unit. Treatment with intravenous steroids, topical steroids and desloratadine was initiated. She subsequently developed Staphylococcus aureus bacteremia and died of multi-organ failure. Toxic epidermal necrolysis is an extremely rare, acute hypersensitivity reaction involving the skin and mucous membranes. Features more suggestive of toxic epidermal necrolysis are acute onset and rapid worsening of painful lesions of the skin and mucous membranes. Specific treatment with active interventions should be practiced in the context of an international and multicentre clinical study in order to give sufficient power for such trials in this rare disease.

A Case of Well-Differentiated Papillary Mesothelioma of the Male Peritoneum: Successful Treatment by Systemic Chemotherapy

Well-differentiated papillary mesothelioma of the peritoneum (WDPMP) is a rare subtype of epithelioid mesothelioma, which is usually seen in young women without a history of asbestos exposure, and generally, has an indolent course. The relative rarity of this neoplasm in males prompted us to report this case of a well-differentiated papillary mesothelioma of the peritoneum in a 36-year-old man.

The patient, who had no history of asbestos exposure, presented with abdominal pain and ascites of unknown etiology. Computed tomography showed abundant ascites with nodules of the peritoneal cavity. Laparoscopic examination revealed a large number of white miliary nodules diffusely covering the peritoneum. Pathology revealed a diagnosis of well-differentiated papillary mesothelioma of the peritoneum, based on histomorphology and immunohistochemistry. The patient started chemotherapy with cisplatin and pemetrexed. After six cycles of chemotherapy, the effectiveness of this chemotherapy was checked by only the computed tomography. PET scan was not used because it is not routinely recommended in WDPMP. Few data are currently available in the literature regarding the performance of the PET scan in WDPMP. Nine months later, the patient was free of symptoms.

Based on reviewing the literature and our observations in this case, consultation of other pathologists is highly recommended to discern WDPMP from other disseminated peritoneal diseases, in order to offer the most effective and safe therapeutic strategy. Chemotherapy should be strongly considered if the tumor is unresectable and accompanied by symptoms. Cisplatin and pemetrexed chemotherapy could be a promising therapeutic choice.

Exophthalmos Revealing a Krukenberg Tumor: A Case Presentation and Review of the Literature

BACKGROUND

Krukenberg tumor is a well-known ovarian metastasis, usually of signet ring cell carcinoma in female patients. In the literature, there are a few documented cases of ocular metastasis in patients with Krukenberg tumor.

CASE PRESENTATION

We report the case of a 35-year-old single Moroccan woman. She presented chronic pelvic pain, hematemesis and blurring of vision in the left eye. Clinical examination showed a pelvic mass and an exophthalmos with a divergent strabismus in the left eye. Pelvic and abdominal ultrasound showed a right tissular ovarian mass. Computed tomography (CT) scan of the abdomen and pelvis revealed an ovarian tumor and bone metastasis. Orbital magnetic resonance imaging (MRI) showed a hypertrophy of the left inferior rectus muscle behind the exophthalmos. Stomach endoscopy revealed an ulcerated and protruded mass of the antro-fundic junction. Histopathology and immunohistochemistry showed an infiltration of the gastric mucosa by atypically isolated signet ring cells similar to the tumor cells found in the ovarian histopathological exams.

DISCUSSION

Krukenberg tumor is an uncommon metastatic tumor of the ovary. This article provides an overview of the major pathological manifestations of Krukenberg tumor, patient characteristics, clinical and laboratory features of the disease, prognostic factors, and current knowledge about its pathogenesis.

An unusual case of isolated peritoneal metastases from lung adenocarcinoma

INTRODUCTION

Peritoneal metastases from lung cancer are a rare event. In this paper, we report the case of a patient with adenocarcinoma of the lungs who had isolated peritoneal metastases at the time of diagnosis.

CASE REPORT

We report a 55-year-old female who presented with shortness of breath, decreased effort tolerance, cough, and weight loss. Her initial chest X-ray and subsequent chest CT showed a 12 × 9 × 8 cm mass in the middle lobe of the right lung. The histopathological examination of her biopsy material was consistent with a thyroid transcription factor-1 positive lung adenocarcinoma. In the abdomen, a 5.3-cm mass was identified. A biopsy and immunohistochemistry revealed a lung adenocarcinoma. The patient was administered chemotherapy based on carboplatin-paclitaxel-bevacizumab, but only with a partial response. Six months later, the patient showed brain metastases. Therefore, a second-line treatment based on pemetrexed was administered for 9 courses, and a clinical and radiological response was observed. The chemotherapy was stopped and the patient did not exhibit any symptoms of progression while waiting for a new evaluation.

DISCUSSION

The incidence of peritoneal involvement of lung cancer without metastases in other parts of the body is scarcely encountered in clinical practice. Out of the different types of lung cancers, adenocarcinoma and large cell carcinoma are most likely to metastasize in the peritoneum. Immunohistochemical staining patterns were important in the differential diagnosis with the other etiologies for peritoneal metastasis and the mesothelioma. Peritoneal metastases are indicative of a disseminated disease and prognosis is extremely poor.

Spinal cord ischemia secondary to transcatheter arterial chemoembolization for hepatocellular carcinoma

Transcatheter arterial chemoembolization (TACE) is accepted worldwide as an effective treatment for patients with unresectable hepatocellular carcinoma. Although considered relatively safe, TACE has been associated with several complications. Spinal cord ischemia secondary to TACE is an extremely rare but disastrous complication. We report a very rare case of spinal cord injuries after TACE, together with a literature review. During the procedure, the patient suddenly experienced sensory impairment below the T10 dermatome and bilateral lower extremity motor weakness. She was given high-dose steroids and supportive therapy. The sensory deficits nearly improved completely, but motor strength remained unchanged. Thereafter, a chest computed tomography scan showed tumor metastasis to the lungs. The patient is now receiving sorafenib and follow-up.

Cardiac metastases of renal cell carcinoma revealed by syncope: diagnosis and treatment

INTRODUCTION

Cardiac metastases from renal cell carcinoma are very rare. In this report, we describe a case of ventricular metastases in the absence of vena cava or right atrial involvement.

CASE REPORT

We report the case of a 60-year-old man who had a past history of heavy tobacco intake and well-controlled arterial hypertension. He experienced sudden-onset palpitations, lost consciousness and, as a result, was involved in an accident on the public highway. Cardiac arrhythmia was suspected and, therefore, transthoracic echocardiography was suggested, which revealed a large right ventricular mass. Chest and abdominal computed tomography demonstrated a mass in the right ventricle, but without contiguous vena cava involvement, and a right renal mass related to the probable neoplasm. An ultrasound-guided renal biopsy showed a clear-cell renal cell carcinoma. A bone scan revealed a metastatic bone disease. The patient was started on sunitinib treatment, which was well tolerated. However, approximately 8 months later, reevaluation showed pulmonary metastases. The patient was subsequently started on treatment with everolimus, which, however, was poorly tolerated. Two months later, the patient died due to terminal respiratory insufficiency.

DISCUSSION

Based on the literature and our observations in this case, targeted antiangiogenic therapy should be considered as a viable therapeutic alternative to metastasectomy for patients with inoperable cardiac metastatic disease as long as there is no baseline systolic or diastolic dysfunction. The case also emphasizes the importance of a thorough history review and physical examination in the workup of patients with syncope.

Primary chondrosarcoma of the breast: a case presentation and review of the literature

Mammary sarcomas are uncommon tumors. When tumors like malignant cystosarcomaphyllodes and metaplastic carcinoma, where malignant cartilaginous areas may be present, are excluded, only nine cases have been reported to date.We report another case of primary chondrosarcoma of the breast here. A 24-year-old Mediterranean woman presented with a painful mass in the right breast and a physical examination revealed a palpable mass. An incisional biopsy was performed and primary chondrosarcoma was diagnosed based on histological examination. Our patient underwent a mastectomy. A preoperative clinical and cytological diagnosis of chondrosarcoma, even though possible in a few cases, is usually not attained due to its similarclinical behavior with other breast tumors.

Is there any advantage to combined trastuzumab and chemotherapy in perioperative setting her 2neu positive localized gastric adenocarcinoma?

We report here a 44-year-old Moroccan man with resectable gastric adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2) by immunohistochemistry who was treated with trastuzumab in combination with chemotherapy in perioperative setting. He received 3 cycles of neoadjuvant chemotherapy consisting of trastuzumab, oxaliplatin, and capecitabine. Afterwards, he received total gastrectomy with extended D2 lymphadenectomy without spleno-pancreatectomy. A pathologic complete response was obtained with a combination of trastuzumab and oxaliplatin and capecitabine. He received 3 more cycles of trastuzumab containing regimen postoperatively.

We conclude that resectable gastric carcinoma with overexpression of the c-erbB-2 protein should ideally be managed with perioperative combination of trastuzumab with chemotherapy. Further research to evaluate trastuzumab in combination with chemotherapy regimens in the perioperative and adjuvant setting is urgently needed.

Treatment of Liver Metastases From Colorectal Cancer: Medico-Surgical Strategies

BACKGROUND

The management of hepatic metastases from colorectal cancer can be understood only as part of a multidisciplinary strategy. Progress experienced by medical treatment, surgical techniques and ways of imaging, has improved the prognosis of patients with liver metastases of colorectal cancers. This work displays the experience of Medical Oncology unit at the Military training hospital in Rabat.

METHODS

From January 2007 to December 2009, 60 patients with liver metastases from colorectal cancer, synchronous or metachronous were supported in the Medical Oncology unit at the Military training hospital in Rabat.

RESULTS

Liver metastases were synchronous in 41 (68%) patients and metachronous in 19 (32%). Patients were classified into 3 categories according to their resectability: 14 (22%) were resectable at the outset, 28 (47%) were unresectable and 18 (31%) were considered uncertain resectability. Thirty-five patients (58%) received neoadjuvant chemotherapy before surgical gesture, 25 (42%) received chemotherapy after resection of primary tumor. This chemotherapy enabled the resection of liver metastases in 5 patients initially deemed uncertain resectability. The average objective responses to chemotherapy were in the range of 59% with 4 complete responses and one confirmed histologically. Twenty-three patients (38%) underwent surgery including 15 liver resections with R0 (25%). The median progression-free survival in this series was 15.5 months. Some minor side effects were noted, which have not entered the prognosis of patients.

CONCLUSIONS

Hepatic resection remains the only potentially curative treatment of liver metastases of colorectal cancers. Perioperative chemotherapy is a promising standard, which has improved the prognosis of patients historically associated with a poor prognosis.

[Primary adenoid cystic carcinoma in breast]

Adenoid cystic carcinoma (ACC) of the breast is a rare neoplasm. We report two observations occurring in female patients, 54 and 65 years old, who consulted for a mastodynia. Clinical examination showed limited painful breast nodules. On ultrasound and mammography they are well-limited bulky mass without microcalcifications. Diagnosis was based on final histopathological exam completed by immunohistochemistry or after slides review. The two patients were treated by mammectomy plus adjuvant radiotherapy and remain alive in remission with a follow-up of 29 and 36 months.
