Rationale: Lung adenocarcinoma is the most common pathologic pattern of lung cancer. During the past decades, a number of targeted agents have been explored to treat advanced lung adenocarcinoma. Recently, Crizotinib, the antagonist of anaplastic lymphoma kinase (ALK), has been widely used in ALK-rearranged lung cancer treatment. Crizotinib is generally well tolerated while its most frequent adverse events include visual disorders, gastrointestinal disturbances, cardiac and endocrine abnormalities. Rash caused by crizotinib is rarely seen, and there are few case reports of severe rash caused by crizotinib.

Patient concerns and diagnoses: Here we report cases of an 81-year-old man and a 66-year-old woman with ALK-rearranged advanced lung adenocarcinoma. When patients came to our department, they both had crizotinib-induced severe rash.

Interventions: Crizotinib was initiated as the 1st-line treatment without other therapies. We treated severe rash with traditional Chinese medicine (TCM) therapy called Zhiyang Pingfu liquid along with Western medicine. Zhiyang Pingfu liquid consists of Scutellaria baicalensis 20 g, Portulaca oleracea 30 g, Cortex Dictamni 30 g, Sophora flavescens 30 g, and other substances. Western medicine includes Minocycline hydrochloride tablets and Aprepitant capsules.

Outcomes: Both patients achieved a partial response when treated with crizotinib, and suffered from severe rash. With Zhiyang Pingfu liquid and Western medicine, their rash gradually disappeared with no sign of cancer progression. Also the male patient did not relieve after taking only antibiotics (standard therapy) and anti-allergic medicine.

Lessons: Despite the dramatic benefit of crizotinib for patients with ALK rearrangement, crizotinib-induced severe rash needs to be dealt with caution. This is the 1st case in which TCM and Western medicine are used to successfully treat crizotinib-induced severe rash. The mechanism of crizotinib-induced rash deserves further attention in future research.

1 Introduction

Lung cancer is the leading cause of cancer-related death worldwide. For certain patients with nonsmall-cell lung cancer (NSCLC), molecularly targeted therapies have transformed treatment and improved overall survival. The most-studied driver pathways are the epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK). For these 2 genetic subtypes, targeted therapies represent the standard care for the superior efficacy and improved tolerability, as compared with cytotoxic chemotherapy.[1,2] Crizotinib is a multi-targeted tyrosine kinase inhibitor (TKI), which is proved to be safe and effective for ALK-rearranged patients with NSCLC.[3,4] In clinical practice, common adverse events associated with crizotinib are vision disorders, gastrointestinal disturbances, cardiac, and endocrine abnormalities and most of them are grade 1 or 2 in severity. It is reported that the occurrence rate of rash is 10%, and with no grades 3 to 4 cutaneous reaction.[5] The mechanism of rash caused by crizotinib remains unclear and there is a lack of relevant literature. This report, in addition to a literature review, presents 2 cases of patients with severe rash (≥grade 3) caused by crizotinib who have been treated with the combination of Zhiyang Pingfu liquid and Western medicine.

2 Case reports

2.1 First case

In December, 2016, an 81-year-old yellow-raced male smoker (700 packs of cigarettes per year) started to have progressively aggravated syndromes of coughing with phlegm and weakness. Computed tomography (CT) scans of chest was obtained on February 4, 2017 in Beijing Hepingli Hospital, which showed multiple nodules in the inferior lobe of his left lung whose maximum diameter was approximately 19 mm. Positron-emission CT (PET-CT) revealed lymphatic metastasis. A week later, adenocarcinoma was diagnosed by fine-needle aspiration biopsy under ultrasonic bronchoscope. Fluorescence in situ hybridization suggested ALK (2p23) chromosome translocation. The patient was diagnosed with adenocarcinoma in the inferior lobe of left lung in the IV period, according to the American Joint Committee on Cancer Staging System, 7th edition.[6]

On February 17, 2017, the patient started to take crizotinib 200 mg PO twice daily. Then the dose was increased to 250 mg 2 weeks later since no obvious side effects were found. However, after 6 days, the patient developed lots of rash which formed like acne. Before seeking medical advice from our department, he had taken a variety of antibiotics (amoxicillin, erythrocin, itraconazole) and anti-allergic medicine (antihistamine), which did not help alleviate the symptoms. Continuous rash severely affected the patient's quality of life. He suffered from insomnia, depression, and even considered a withdrawal of crizotinib treatment.

Later, the patient was recommended to our Department of Integrative Oncology in China-Japan Friendship Hospital for the treatment of skin toxicity (Fig. 1A–C). Papules were concentrated on his chest and back. Pustules were mainly on his cheeks and the top of his head. The skin lesion totally covered >30% body surface area. Therefore, the level of adverse event was evaluated as grade 3, referring to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 4.0 (NCI-CTCAE v4.0).[7] The therapeutic effect for tumors was also reviewed. CT scans of chest revealed that multiple nodules whose maximum diameter was approximately 4.5 mm were found in the inferior lobe of his left lung. The patient achieved a partial response compared to the last CT result. Zhiyang Pingfu liquid and Western medicine were jointly used to treat skin toxicity.

Figure 1

Zhiyang Pingfu liquid[8–11] consisted of Scutellaria baicalensis 20 g, Portulaca oleracea 30 g, Cortex Dictamni 30 g, and Sophora flavescens 30 g. First, Chinese medical herbs were extracted with water twice, then decompressed and concentrated to the density of 1.10 (60°C), finally centrifugated. Second, medical soup, glycerol, and honey were prepared in a proportion of 2.2:1:2, and then compressed the compound into facial masks. Zhiyang Pingfu liquid could be kept at normal temperature. The Chinese herbs were provided by Tongrentang of Beijing (a time-honored TCM pharmacy in China), and the herbal preparation was completed by pharmacists in the chemical chamber of China-Japan Friendship Hospital.

Zhiyang Pingfu liquid was for topical application. We used the facial mask made of Zhiyang Pingfu liquid for 30 minutes twice or thrice a day on the patient's cheeks. The liquid was also applied to the pustules on the scalp and the papules on his chest and back directly for 30 minutes twice or thrice a day. The patient was required not to clear excretion. Due to the large area of rash, we suggested the patient drop Zhiyang Pingfu liquid into bath water and soak in it for 30 minutes before going to sleep. We also asked the patient to take Minocycline hydrochloride tablets (Wyeth Pharmaceuticals Company, Suzhou, China; approval number: H10960010) 100 mg bid and Aprepitant capsules (Merck Sharp & Dohme Australia Pty Ltd, Hangzhou, China; approval number: H20130545) 125 mg day 1, 80 mg day 2, 80 mg day 3 in the morning orally.

Three days later, the skin rash and itching, especially the pustules on the head, relieved, then the patient could fall asleep. The skin toxicity (Fig. 1D–F) was graded as Cutaneous G2 reaction. The rash and itching disappeared and the skin returned to normal (Fig. 2) after another 7 days.

2.2 Second case

A 62-year-old female, nonsmoker, complained of coughing with little white phlegm, chest distress, and short of breath. CT scans of her chest in the local hospital revealed that there was an unknown neoplasm in the inferior lobe of her left lung. On September 10, 2013, poorly differentiated adenocarcinoma with metastatic carcinoma of lymph nodes was diagnosed by fine-needle aspiration biopsy under ultrasonic bronchoscope in Cancer Hospital Chinese Academy of Medical Sciences. Immunohistochemistry staining revealed ALK-VentanaD5F3 (3+) expression. PET-CT revealed adenocarcinoma in the inferior lobe of her left lung, with metastasis of mediastinal lymph node, bone, abdominal lymph nodes, and liver.

At 1st, the patient received the 1st-line chemotherapeutic regimen of pemetrexed 776 mg day 1 and carboplatin 651 mg day 1, every 21 days, totally 6 periods. During the chemotherapy, she once had grade II bone marrow suppression and grade II gastrointestinal reaction. Terminally, she had a partial response. Then, the patient was treated with crizotinib, 250 mg twice a day. During the treatment, the patient had regular reviews of the CT scans of her chest and abdomen and got a partial response (Fig. 3).

Figure 3

After being treated with crizotinib for about 3 months, the patient developed multiple erythematous rash that spread to upper limbs, cheeks, and neck. Later, she was recommended to our Department of Integrative Oncology in China-Japan Friendship Hospital. Her skin toxicity was observed (Fig. 4A–D). There were multiple rash and erythema on her upper limbs, cheeks, neck, and auricle, some of which were in escharosis and exfoliation, covering >30% body surface area. Simultaneously, the patient complained of the photosensitivity of rash and erythema, which would aggravate when exposed to sunshine. Also, she had skin itching and dryness which severely affected her sleep and daily activities. The skin toxicity was evaluated as grade 3, referring to NCI-CTCAE v4.0.[7]

Figure 4

Figure 4

The skin biopsy specimen (Fig. 5) showed perivascular lymphocytic infiltrates in the upper dermis. The patient was offered the same therapeutic schedule as the 1st case. After 5 days of treatment, rash and erythema (Fig. 4E–H) relieved evidently. Without skin itching, the patient was able to fall asleep. The 2-month follow-up showed the skin toxicity (Fig. 6) disappeared.

For some time, the patient's condition was stable and rash never relapsed. After about 10 months, the patient was diagnosed with brain metastasis and treated with total brain radiotherapy. The patient gradually weakened and passed away due to dyscrasia in the terminal stage of cancer.

3 Discussion

Crizotinib is a multi-target TKI with clinical activity as an ALK inhibitor, which is a selective ATP-competitive small-molecule inhibitor of receptor tyrosine kinases, targeting genes of ALK, MET, proto-oncogene tyrosine kinase c-ROS 1 (ROS1), and so on.[12] In clinical practice, adverse events associated with crizotinib include vision disorders, gastrointestinal disturbances, cardiac and endocrine abnormalities, and most of them are grade 1 or 2 in severity. Reports about incidence rate of crizotinib-induced rash are rare, and we only obtained 2 articles. One reported the rash occurred in 8 patients (11%),[13] and the other in 25 patients (10%),[5] all cases with grade 1 or 2 cutaneous reaction. Thus, crizotinib-induced severe skin rash may be rare in the general population.

We report 2 patients with ALK-positive metastatic lung adenocarcinoma both of whom had a significant response to crizotinib therapy but had difficulty continuing due to severe skin toxicity. They were both qualified as grade III referring to NCI-CTCAE v4.0.[7] But the manifestation of skin toxicity was different. The male was manifested by papules on chest and back, and pustules mainly on cheeks and head, while the female was manifested by multiple rash and erythema on the upper limbs, cheeks, neck, and auricle, and some of which were in escharosis and exfoliation. The female patient also complained of the photosensitivity of rash and erythema, which would aggravate when exposed to sunshine. Both of them had severe pruritus affecting their sleep and daily activities. Neither of them took any other prescribed medicine except crizotinib. Moreover, neither had prior history of allergies nor had any clinical findings suggesting that the rash was associated with an infectious disease. So rash must be caused by crizotinib. Besides, the male patient had taken multiple kinds of antibiotics (amoxicillin, erythrocin, itraconazole) and anti-allergic medicine (antihistamine), but they did not help alleviate the symptoms.

Zhiyang Pingfu liquid has been proved effective for the treatment of rash caused by epidermal growth factor receptor inhibitors (EGFRIs) according to various randomized clinical trials,[8–11] and has functions of anti-inflammation and regulating immunity. From the skin pathology of the female patient, we consider this type of skin toxicity be related to the immunity and inflammation. According to recent research, EGFRI-induced rash originates from immune and inflammatory reactions of keratinocytes.[14] We speculate the mechanism of crizotinib-induced rash may be similar to the EGFRI-induced rash. Therefore, we applied Zhiyang Pingfu liquid for external application. The main phytochemical ingredients of Zhiyang Pingfu liquid are baicalin and baicalein from S baicalensis, sophocarpidine from S flavescens, dictamnine from Cortex Dictamni, extractive from P oleracea. Modern research has proved that baicalein can inhibit expression of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, so it is evidently anti-inflammatory.[15] Baicalin can absorb ultraviolet ray,[16] which may be beneficial for photosensitive rash of the female patient, and has the function of anti-anaphylaxis.[17] Sophocarpidine can evidently inhibit secretion and expression of IL-6.[18,19] Monocase compounds of sophocarpidine can inhibit generation of TNF-α, interferon-γ, and IL-6.[20]P oleracea has rich P oleracea which can promote growth of epithelial cells and ulcer healing.[21] Therefore, we think Chinese herbal compound Zhiyang Pingfu liquid has the functions of anti-inflammation, anti-anaphylaxis, and promoting repair of epidermal cells.

Simultaneously, we asked patients to take Minocycline hydrochloride tablets (Wyeth Pharmaceuticals Company; approval number: H10960010) and Aprepitant capsules (Merck Sharp & Dohme Australia Pty Ltd; approval number: H20130545). Minocycline has the function of anti-inflammation in the whole body. Antibiotics such as Minocycline were recommended for treating skin rash referring to NCI-CTCAE 4.[7] But the male patient did not improve by taking multiple kinds of antibiotics (amoxicillin, erythrocin, itraconazole). Consequently, we suggest the simultaneous use of Minocycline and Zhiyang Pingfu liquid. Both patients had severe pruritus disturbing their sleep and daily activities, so we used Aprepitant which is anti-itching and has been used to treat Erlotinib-induced pruritus (NSCLC),[22,23] and Nivolumab-induced pruritus (NSCLC).[24] Rash and pruritus were evidently relieved upon the 3- to 5-day treatment. The skin recovered to normal after 1 to 2 weeks. In addition, both patients took crizotinib regularly, without a withdrawal or reduction of the dose during the treatment. The follow-up yielded no relapse of their skin toxicity.

Databases such as PubMed, Web of Science, and Cochrane Library were searched to explore how other doctors in the world treated the crizotinib-induced severe skin rash. A total of 5 case reports[14,25–28] were found up to April 2018 (Table 1). It is shown that women may be more likely to have crizotinib-induced severe skin toxicity (4/5); the appearance of skin toxicity after crizotinib administration is irregular; the clinical characteristics of skin toxicity are various such as erythematous rash with photosensitiveness, erythema multiforme, etc. Due to severe skin toxicity, all patients reported temporary reduction or withdrawal of crizotinib,[13–16] or even gave up crizotinib treatment.[13] Two patients were treated with diphenhydramine 1st and then the desensitization clinical protocol. Their skin toxicity never recurred, but neither of them received skin biopsy of rash for mechanism analysis. One patient took a rapid oral desensitization protocol and it worked well.[16] The other patient took methylprednisolone, but it did not work.[13] To our knowledge, this is the 1st report of treating crizotinib-induced severe rash successfully without withdrawing or reducing the dose. Dose reduction may cause tumor progression; therefore, combined treatment of Zhiyang Pingfu liquid and Western medicine deserves to be recommended.

Further studies and clinical experience are necessary to explore the mechanism of crizotinib-induced rash. Also, the combination of Zhiyang Pingfu liquid and Western medicine should be examined in a large number of patients to confirm their usefulness for treating ALK-TKI-induced skin toxicity. Alectinib, the 2nd generation of ALK inhibitors has come into the market, and in the AF-001 JP study, 1% of the patients developed a grade 3 rash.[29] There was a case[30] that reported the successful desensitization protocols therapy in treating alectinib-induced rash. It is hoped that this article would provide insights into methods of treating severe rash caused by crizotinib, even alectinib, and other targeted drugs, especially when antibiotics and anti-allergic medicine are ineffective.

4 Conclusion

Combination of Zhiyang Pingfu liquid and Western medicine could be a recommendation for ALK-rearranged patients with NSCLC with severe crizotinib-induced skin toxicity. To date, this is the 1st report of treating crizotinib-induced severe rash without withdrawing or reducing the dose. However, further studies and clinical experience are needed to explore the mechanism and the therapeutic efficacy.
