Cha, Kim, Choe, Kim, Kim, Hyun, Jung, Koo, Jung, and Yim: A case report of a patient presented with skin ulcer after treatment of lenvatinib

Abstract

A 60-year-old man diagnosed with unresectable hepatocellular carcinoma (HCC) presented to the hospital with pain in the perineal region. He had been taking lenvatinib every day for 2 months after he was diagnosed with HCC with metastases to the lymph node, small bowel mesentery, and retroperitoneal space. Enhanced abdominal computed tomography revealed mild elevation in intensity in the perineal subcutaneous tissue with subcutaneous emphysema. The patient was diagnosed with Common Terminology Criteria for Adverse Events grade 3, skin ulceration of stage IV with full-thickness skin loss and tissue necrosis in the muscular layer. The patient was taken off the medication with prescription of antibiotics, and after 3 weeks, the skin has fully recovered. This is the first report of an HCC patient who presented with a skin ulceration of stage IV after lenvatinib treatment. We recommend stopping the medication immediately and changing to alternative treatments with appropriate supportive care.

INTRODUCTION

Lenvatinib is used as an alternative anti-cancer drug in patients with unresectable hepatocellular carcinoma (HCC) who have previously failed to primary anticancer therapy or sorafenib.1 Lenvatinib acts as an inhibitor of vascular endothelial growth factor receptors-1, 2, 3 and fibroblast growth factor receptors,2 and in the REFLECT study, patients diagnosed with unresectable liver cancer treated with lenvatinib showed non-inferiority to sorafenib, which lead to its approval by the Food and Drug Administration of the United States in 2018.3 In addition, according to a study by Liu et al.4, combination of lenvatinib and pembrolizumab therapy showed superiority to sorafenib. However, lenvatinib is also known to cause side effects such as high blood pressure, diarrhea, fatigue, decreased appetite and weight, nausea, vomiting, and stomatitis.5 Occurrence of cutaneous ulcers after lenvatinib treatment is rare.6,7 Herein, we present a rare case of a patient who developed a cutaneous ulcer after lenvatinib treatment for an unresectable HCC.
This case report is described according to the CARE guidelines available from https://www.care-statement.org/. The ethics committee of Korea University Ansan Hospital approved of this study (IRB approval number: 2021AS0225), and waived the requirement for informed consent.

CASE REPORT

A 60-year-old man visited the emergency department complaining of perineal pain and an ulcerative cutaneous lesion. Four months prior to this visit, he had visited the hospital with abdominal distension, and was diagnosed with chronic hepatitis B and HCC. He also had a history of alcohol abuse, drinking one bottle of soju every day for 20 years. He was never a smoker, and did not have any other medical or surgical history.
A three-phase computed tomography (CT) at that time demonstrated an HCC with metastases to the lymph nodes in the porta hepatis, small bowel mesentery and retroperitoneal space. Carcinoma peritonei was suspected, and portal vein thrombosis (PVT) was also present (Fig. 1). Primovist liver magnetic resonance imaging showed an infiltrative HCC with intrahepatic metastases in both hepatic lobes, with tumor thrombi in the main and right portal veins as well as the right hepatic vein. Due to multiple lymph node metastases in the porta hepatis with suspicious seeding nodules in the right lower abdominal cavity, the patient was diagnosed as HCC, Barcelona Clinic Liver Cancer stage C. Hence, he was started on treatment with lenvatinib.
At the time of his second visit, he was on lenvatinib 12 mg every day, with concurrent radiotherapy for the PVT. His body weight was 65.8 kg, and his Eastern Cooperative Oncology Group status was 0.
After taking lenvatinib for 2 months, he visited the emergency room complaining of pain in the perineal area. He seemed to be in acute pain with vital signs as follows: blood pressure of 150/104 mmHg, heart rate of 84/min, respiratory rate of 16/min, and body temperature of 36.9. He was alert without icteric sclera. Chest auscultation revealed normal breath sounds and his heartbeat was regular without murmurs. On abdominal examination, his abdomen was soft without rigidity, and his liver and spleen were not palpable. Neurological examination was unremarkable. On examining the skin, an ulcerative skin lesion was observed in the perineal area, extending from behind the right scrotum to the anus (Fig. 2).
Initial laboratory findings were as follows: hemoglobin 16.6 g/dL, white blood cell count 5,800/μL (neutrophil 73.3%, lymphocyte 14.3%, monocyte 11.9%, eosinophil 0.2%, basophil 0.3%), platelet count 188,000/μL, blood urea nitrogen 30.2 mg/dL, serum creatinine 1.25 mg/dL, asparate aminotransferase 92 IU/L, alanine aminotransferase 25 IU/L, total bilirubin 1.89 mg/dL, direct bilirubin 0.92 mg/dL, total protein 2.8 g/dL, albumin 2.8 g/dL, and C-reactive protein (CRP) 9.93 mg/dL.
Enhanced abdominal CT demonstrated no evidence of abscess, but high attenuation was observed in the subcutaneous tissue, which was interpreted as being most likely due to inflammation and subcutaneous emphysema caused by the ulcer. There was no significant difference in the size of the hepatic mass and the adjacent lymph node compared to the CT scan taken 2 months ago.
The patient was diagnosed with CTCAE grade 3, skin ulceration of stage IV due to lenvatinib treatment, with full-thickness skin loss and tissue necrosis.8 He immediately stopped taking lenvatinib, a wet gauge dressing was applied, and piperacillin/tazobactam was prescribed. He experienced severe pain, and on the third day, the laboratory examination showed an increase in CRP level to 13.95 mg/dL. Therefore, on the fourth day, the patient underwent an incision of the necrotic tissue under local anesthesia. The largest skin ulcer measured about 4×3 cm and no other complication was observed during the surgery. After 10 days of antibiotics and conservative treatment following the surgical incision (Fig. 2), the patient was discharged, with healing of the cutaneous lesion, amelioration of the pain, as well as a decrease in the CRP level to 5.05 mg/dL. He was educated to self-disinfect the cutaneous lesion, and full recovery was noted after 3 weeks.

DISCUSSION

Lenvatinib is a type I tyrosine kinase inhibitor with antiangiogenic activity.9,10 Due to this property, lenvatinib is used to treat liver cancer, differentiated thyroid cancer and renal cell carcinoma, and there are recent studies that have also demonstrated its effectiveness on medullary and anaplastic thyroid cancer, as well as endometrial cancer.11,12
However, lenvatinib is also known for its various side effects, such as hypertension, diarrhea, nausea, vomiting and hypothyroidism. In addition to these side effects, cutaneous adverse effects have also been reported.5,13 Previous studies have reported complications including palmar-plantar erythrodysesthesia (27% to 32%), skin rash (14% to 21%), alopecia (12%), hyperkeratosis (7%), and wound healing impairment (<1%).14,15 However, there is a limited number of studies reporting skin ulceration as a side effect; a thorough search for documented case reports retrieved two case studies of ulcer formation after lenvatinib treatment. Kitamura et al.7 reported a case of a cutaneous ulcer that occurred in the subclavicular area of a patient with relapsed thyroid cancer after treatment with lenvatinib. Lenvatinib was immediately ceased and a pectoralis major myocutaneous flap was grafted over the ulcerated lesion. However, this case was different from our present case, as the cutaneous lesion occurred close to the site of the primary cancer. Dohmen6 reported a case of a palmar-plantar erythrodysesthesia in an HCC patient after lenvatinib treatment which recurred within 3 weeks after restarting the drug, after a 4-week-long withdrawal period. The recurrent palmar-plantar erythrodysesthesia was accompanied by an ulcerative cutaneous lesion in the thigh. The skin lesion, CTCAE grade 2, was erythematous with partial thickness loss in transitional stage to formation of a new skin. The lesion disappeared about 4 weeks after discontinuation of the medication and application of prostaglandin ointment.6 This case is quite similar to our case as the skin lesion was formed distant from the primary tumor; however, the skin lesion was not as severe as in our case. Our case is the first case of a cutaneous ulcer after lenvatinib treatment with a CTCAE grade of 3, that was observed in a distant location from the primary cancer. The precise mechanism by which lenvatinib causes cutaneous ulceration is not fully understood, but platelet-derived growth factor receptor inhibition by lenvatinib may play a role in impairing the tissue repair process.8
The withdrawal period of lenvatinib and the treatment ulcer formation due to lenvatinib, has yet to be established. In the case reported by Kitamura et al.7, lenvatinib was ceased for 20 days and was restarted after the surgery; however, after 1 month of restarting lenvatinib, they stopped again due to fistula formation and discharge through the fistula. Similarly, in Dohmen’s case report, the palmar-plantar erythrodysesthesia recurred with stage II ulcer on restarting the medication after a 4-week withdrawal period, and the medication had to be stopped again.6 Therefore, both case reports demonstrate that the cutaneous lesion recurred or worsened after restarting lenvatinib. In contrast, our case showed severe skin ulceration of stage IV even when the lenvatinib was not restarted. Therefore, close observation and immediate cessation of lenvatinib is warranted when a cutaneous ulcer is detected, and alternative medications should be strongly considered.
This is the first case report of an HCC patient who presented with skin ulceration of stage IV after treatment with lenvatinib. We recommend quitting the medication immediately and also changing to alternative treatment even when the lesion shows significant improvement after appropriate supportive measures.
