Second primary head and neck squamous cell cancers with aggressive behavior in patients with chronic myeloid leukaemia

A Rare Case of Dual Metachronous Primary Malignancies, Chronic Myeloid Leukemia, and Tongue Carcinoma in a Patient With Long-Standing Systemic Lupus Erythematosus: A Case Report and Review of Literature

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor. Although squamous cell carcinoma (SCC) of the skin has been reported in CML patients, mucosal SCC of the head and neck has rarely only been reported in CML survivors. The objective of this case report is to share our experience in treating a patient with dual metachronous primary malignancies, CML, and tongue carcinoma, along with long-standing SLE, managed by a multidisciplinary team.

Are second primary head and neck cancers with previous hematological malignancy more aggressive than de novo head and neck cancers?

OBJECTIVES

Secondary solid tumors can occur after the treatment of hematological malignancies and are associated with a poor prognosis. We evaluated the survival outcomes of patients with second primary head and neck cancers according to the site of cancer origin, type of hematological malignancy, and age.

MATERIALS AND METHODS

We enrolled all patients who underwent surgery for second primary head and neck cancer and were previously treated for hematological malignancy between 1997 and 2020. We analyzed the survival outcomes of patients with second primary head and neck cancer, and compared them with 3126 de novo head and neck cancer patients diagnosed during the same period at our hospital.

RESULTS

The 5-year overall survival (OS) rate was significantly worse for second primary head and neck cancer patients than de novo cancer patients (52.0 % and 77.9 %, respectively; p = 0.04) and those results were similarly observed in second primary oral cavity cancer (33.3 % and 75.7 %, respectively; p < 0.01). Patients with myelodysplastic syndrome and acute myeloid leukemia showed significantly worse 5-year OS rate than those with other types of hematological malignancies (p = 0.036). Multivariate analysis showed that bone marrow transplantation (BMT) was a risk factor for the recurrence of head and neck cancers (odds ratio = 6.635, p = 0.042).

CONCLUSION

Patients with second primary head and neck cancer, particularly of the oral cavity, had a worse prognosis than patients with de novo head and neck cancer. BMT predicts recurrence in second primary head and neck cancer patients.

In situ buccal carcinoma in a teenager after hematopoietic stem cell transplantation: A case report

RATIONALE

Hematopoietic stem cell transplantation (HSCT) is the most effective treatment for the majority of patients who have malignant haemolytic disease. Although the success rate of HSCT has increased, the increasing number of cases suffering from secondary solid malignancies after HSCT has attracted more interest recently.

PATIENT CONCERNS

A 16-year-old female patient from China presented with a crusty and painful lesion on the left buccal mucosa with a history of chronic graft-versus-host disease following allogeneic HSCT for acute myeloid leukaemia.

DIAGNOSIS

An incisional biopsy of the lesion showed stratified squamous epithelium mucosa with severe dysplasia (carcinoma in situ). Subsequently, a wide local excision was performed and histological examination revealed early infiltrating squamous epithelial mucosa (carcinoma in situ).

INTERVENTIONS

She was being treated in the oral and maxillofacial surgery clinic with an incisional biopsy of the left buccal mucosa. She also received a wide local excision.

OUTCOMES

Follow-up for 4 years showed no recurrence.

LESSONS

This case helps raise awareness of the diagnosis of oral symptoms in young patients after HSCT. Due to the increasing application of HSCT, raising awareness in oral and dental physicians may be required to improve long-term clinical outcome of patients who underwent HSCT.

Risk of Head and Neck Cancer in Patients With Prior Hematologic Malignant Tumors

Importance

More than 1.3 million people in the United States have a hematologic malignant tumor currently or in remission. Previous studies have demonstrated an increased risk of secondary neoplasms in patients with hematologic malignant tumors, but research specifically on the risk of head and neck solid tumors in patients with prior hematologic malignant tumors is limited.

Objectives

To examine a possible association between prior hematologic malignant tumors and risk of head and neck cancer and to assess the overall survival (OS) among these patients.

Design, Setting, and Participants

This retrospective analysis used the Veterans Affairs (VA) Corporate Data Warehouse (CDW) to identify patients with diagnoses of hematologic malignant tumors and head and neck cancers. All patients in the VA CDW with a birthdate between January 1, 1910, and December 31, 1969, were included, for a cohort of 30 939 656 veterans. Data analysis was performed from August 15, 2018, to January 31, 2019.

Exposures

Outpatient problem lists were queried for diagnoses of hematologic malignant tumor and associated malignant tumors using International Classification of Diseases, Ninth Revision (ICD-9) and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes to categorize patients by history of hematologic malignant tumors.

Main Outcomes and Measures

Presence of head and neck cancer was determined from ICD-9 and ICD-10 codes of outpatient problem lists, and cancers were grouped by subsite. The OS was determined from date of death or last outpatient visit date.

Results

Of 30 939 656 patients (27 636 683 [89.3%] male; 13 971 259 [45.2%] white), 207 322 patients had a hematologic malignant tumor, of whom 1353 were later diagnosed with head and neck cancer. A history of hematologic malignant tumors was significantly associated with overall aerodigestive tract cancer, with a relative risk (RR) of 1.6 (95% CI, 1.5-1.7), as well as oral cavity (RR, 1.7; 95% CI, 1.5-1.9), oropharynx (RR, 1.7; 95% CI, 1.5-1.9), larynx (RR, 1.3; 95% CI, 1.2-1.5), nasopharynx (RR, 2.8; 95% CI, 2.1-3.9), sinonasal (RR, 3.0; 95% CI, 2.2-4.1), salivary gland (RR, 2.8; 95% CI, 2.4-3.3), and thyroid (RR, 2.1; 95% CI, 1.9-2.4) tumors on subsite analysis. A prior hematologic malignant tumor was also negatively associated with 2-year and 5-year OS for multiple subsites.

Conclusions and Relevance

A prior diagnosis of hematologic or associated malignant tumors was associated with an increased risk of solid head and neck cancers in a range of subsites. In addition, for several head and neck cancer subsites, patients with prior hematologic malignant tumors had worse 2-year and 5-year OS. These results indicate that a prior hematologic malignant tumor may be an adverse risk factor in the development and progression of head and neck cancer.

Incidence of adrenal gland tumor as a second primary malignancy: SEER-based study

PURPOSE

Advances in cancer treatment achieved during the past decades have resulted in increased survival of most pediatric and adult patients that suffered from different adrenal tumor types. This article reviews the incidence and survival of adrenal gland tumors as second primary tumors, according to data from the Surveillance, Epidemiology, and End Results (SEER) database.

METHOD

The SEER 13 Registries Database from 1992 to 2013 was used. All primary cancer sites were selected using the Multiple Primary Standardized Incidence Ratios (MP-SIR) session.

RESULTS

Data for a total of 2,887,468 persons with cancer were reviewed. 117 of whom had suffered second primary adrenal tumors. The overall standardized incidence ratio (SIR) of adrenal gland tumor as a second primary was 1.49. A high incidence ratio of the event was also detected in specific primary tumor sites: hypopharynx (Observed/Expected(O/E) = 44.59); other endocrine tissue (including the thymus) (O/E=38.27); chronic myeloid leukemia (O/E=11.15); small intestine (O/E=8.86); liver (O/E=8.74); stomach (O/E=4.95); nodal NHL (O/E=3.79); kidney and renal pelvis (O/E=3.19); and breast (O/E=1.78).

CONCLUSION

The underlying shared mechanisms should be investigated between adrenal tumors and hypopharyngeal, endocrine and other tumors. Racial disparity is an important challenge in cancer treatment at US and should be taken into consideration in the design of cancer prevention programs. This could be achieved through follow-up programs at specialized national cancer networks, especially for rare tumors like adrenal gland.

CML as Part of Dual Malignancies-A Retrospective Analysis: Possible Mechanisms and Review of Literature

Introduction of imatinib has changed the outlook of chronic myeloid leukaemia (CML) patients with overall survival approaching general population. Long term survival in CML patients has provided an opportunity to better study natural history and long term complications of disease as well as the treatment modalities. To study the occurrence and association of other malignancies with their outcomes in patients with CML. This is a single centre retrospective study. All CML patients case records registered with haematology clinic of a tertiary care centre in North India from 2001 to 2014 were perused and evaluated for dual malignancies. Those patients with dual malignancies were personally examined and interviewed if alive. Out of 1677 patients, 15 cases had co-existent malignancies. Four of fifteen cases of dual malignancies had CML as secondary cancer. Three had synchronous and rest 12 patients had metachronous malignancies. Only one patient was in accelerated phase, rest all were in chronic phase. Median age of the dual malignancy cases was 50 years (25-66 years), much younger than reported in west. The initial dose of imatinib was 400 mg OD in all except one. We did not find any causal association between CML or imatinib therapy with development of secondary tumours. Interestingly in this series, incidence of CML as secondary or synchronous malignancy was higher than earlier published studies.

Synchronous presentation of chronic myeloid leukemia with carcinoma penis: a rare presentation

We report here a case of 52-year-old male presenting with penile ulcer. On evaluation, he was diagnosed to have Carcinoma penis with concurrent CML in chronic phase. Clinical examination showed pallor, bilateral inguinal lymphadenopathy, bilateral pitting pedal oedema and hepatosplenomegaly. He was diagnosed to have chronic myeloid leukemia based on peripheral smear examination showing raised counts with shift to left and fluorescence in situ hydridisation (FISH) showing t (9:22). The ilio-inguinal block dissection specimen showed inguinal metastasis of squamous cell carcinoma (SCC). This case is being presented here in view of the rarity in combination of CML with another malignancy.
