Lessons Learned
- Androgen receptor as assessed by immunohistochemistry is expressed in a high proportion of patients with hepatocellular carcinoma (HCC).
- Enzalutamide at 160 mg orally daily is safe and tolerable in patients with advanced HCC but has no single‐agent antitumor activity.
- Enzalutamide, a CYP3A4 inducer, at a standard dose of 160 mg reduces the exposure of sorafenib, a CYP3A4 substrate.
- Enzalutamide and sorafenib is safe and tolerable in patients with advanced HCC, but the addition of enzalutamide to sorafenib did not enhance the antitumor activity of sorafenib.

The optimal management of advanced non‐small cell lung cancer (NSCLC) with noncanonical epidermal growth factor receptor (EGFR) mutations (i.e., exon 19 deletion and exon 21 L858R) is constrained by the heterogeneous behavior of individual uncommon mutations and limited prospective clinical data in this setting. Despite encouraging results with osimertinib from a recently published phase II trial from South Korea, afatinib remains the only currently approved drug for patients with tumors harboring uncommon EGFR mutations (i.e., S768I, L861Q, and/or G719X). When used at the standard dose of 40 mg daily, afatinib is associated with significant rates of treatment‐related adverse events, leading to frequent dose reductions and treatment discontinuations. We report a case of a woman with advanced NSCLC harboring EGFR‐G719A mutation treated with afatinib (at an off‐label pulse dose strategy that merits further evaluation in prospective studies) with sustained partial response for 20 months with manageable expected toxicities. Subsequent disease progression was mediated by off‐target pan‐EGFR inhibitor (including osimertinib)–resistant KRAS mutation and not by acquisition of EGFR‐T790M. We further present the current state of evidence in the literature behind use of first‐, second‐, and third‐generation tyrosine kinase inhibitors and summarize the evolving spectrum of activity ascribed to osimertinib (and newer EGFR inhibitors with a more favorable therapeutic window and intracranial penetration) in this population of patients with advanced NSCLC and uncommon EGFR mutations.Key Points
- Uncommon EGFR mutations characterize a heterogeneous group of patients with advanced non‐small cell lung cancer (NSCLC).
- Afatinib is the only currently U.S. Food and Drug Administration–approved drug for management of advanced NSCLC with uncommon EGFR mutations (S768I, L861Q, and/or G719X).
- Afatinib treatment at 40 mg daily is associated with high rates of adverse events and dose reductions; alternative strategies including pulse intermittent dosing should be evaluated prospectively.
- Osimertinib (with favorable safety profile and intracranial penetration) has shown promising results in this population in a phase II trial from South Korea; additional trials are ongoing.

We report on a woman with aggressive estrogen receptor‐positive, KRAS‐mutated ovarian cancer who achieved a remarkable response to combination therapy with the MEK inhibitor (trametinib) and the aromatase inhibitor (letrozole), even though the disease had failed to respond to a combination of a PI3K inhibitor and different MEK inhibitor, as well as to trametinib and the estrogen modulator, tamoxifen, and to letrozole by itself. The mechanism of action for exceptional response was elucidated by in vitro experiments that demonstrated that the fact that tamoxifen can have an agonistic effect in addition to antagonist activity, whereas letrozole results only in estrogen depletion was crucial to the response achieved when letrozole was combined with an MEK inhibitor. Our current observations indicate that subtle variations in mechanisms of action of outwardly similar regimens may have a major impact on outcome and that such translational knowledge is critical for optimizing a precision medicine strategy.Key Points
- This report describes the remarkable response of a patient with KRAS‐mutated, estrogen receptor‐positive low‐grade serous ovarian cancer treated with trametinib (MEK inhibitor) and letrozole (aromatase inhibitor), despite prior progression on similar agents including tamoxifen (estrogen modulator).
- In vitro investigation revealed that tamoxifen can have agonistic in addition to antagonistic effects, which could be the reason for the patient not responding to the combination of trametinib and tamoxifen.
- The current observations suggest that drugs with different mechanisms of action targeting the same receptor may have markedly different anticancer activity when used in combinations.

Lessons Learned
- A biweekly TAS‐102 plus BEV schedule in patients with heavily pretreated mCRC showed equivalent efficacy with less toxicity compared with the current schedule of TAS‐102 plus BEV combination.
- Biweekly TAS‐102 plus BEV combination could reduce unnecessary dose reduction of TAS‐102, maintain higher doses, and possibly be effective even in cases without chemotherapy‐induced neutropenia (CIN).
- The prespecified subgroup analysis of this study showed an obvious association between CIN within the first two cycles and prognosis of biweekly TAS‐102 plus BEV.

Lessons Learned
- Treatment for patients with metastatic colorectal cancer (mCRC) typically involves multiple lines of therapy with eventual development of treatment resistance.
- In this single‐arm, phase II study involving heavily pretreated patients, the combination of sorafenib and capecitabine yielded a clinically meaningful progression‐free survival of 6.2 months with an acceptable toxicity profile.
- This oral doublet therapy is worthy of continued investigation for clinical use in patients with mCRC.

Lessons Learned
- Afatinib and selumetinib can be combined in continuous and intermittent dosing schedules, albeit at lower doses than approved for monotherapy.
- Maximum tolerated dose for continuous and intermittent schedules is afatinib 20 mg once daily and selumetinib 25 mg b.i.d.
- Because the anticancer activity was limited, further development of this combination is not recommended until better biomarkers for response and resistance are defined.

Patients with non‐small cell lung cancer (NSCLC) containing ROS1 fusions can have a marked response to the ROS1‐targeted tyrosine kinase inhibitors (TKIs), such as crizotinib. Common resistance mechanisms of ROS1‐fusion targeted therapy are acquired mutations in ROS1. Along with the use of next‐generation sequencing in the clinical management of patients with NSCLC during sequential targeted therapy, many mechanisms of acquired resistance have been discovered in patients with activated tyrosine kinase receptors. Besides acquired resistance mutations, bypass mechanisms of resistance to epidermal growth factor receptor (EGFR)‐TKI treatment are common in patients with EGFR mutations. Here we describe a patient with metastatic lung adenocarcinoma with CD74‐ROS1 fusion who initially responded to crizotinib and then developed resistance by the acquired mutation of D1228N in the MET kinase domain, which showed short‐term disease control for cabozantinib.Key Points
- The D1228N point mutation of MET is an acquired mutation for crizotinib resistance.
- The patient obtained short‐term clinical benefit from cabozantinib therapy after resistance to crizotinib.
- The clinical use of next‐generation sequencing could maximize the benefits of precision medicine in patients with cancer.

Lessons Learned
- This is the first trial to explore the neoadjuvant therapy of pyrotinib in HER2‐positive operable and locally advanced breast cancer, in combination with epirubicin plus cyclophosphamide followed by docetaxel plus trastuzumab.
- Results primarily showed that pyrotinib in combination with epirubicin plus cyclophosphamide followed by docetaxel plus trastuzumab was effective and safe in HER2‐positive operable and locally advanced breast cancer.
- A subsequent randomized controlled trial is still warranted to confirm these results.

Lessons Learned
- Monotherapy with prexasertib demonstrated modest activity in BRCA wild‐type, recurrent triple‐negative breast cancer, highlighting the unmet need for combination treatment strategies.
- Neutropenia, anemia, and thrombocytopenia are common with the use of prexasertib but are manageable with supportive care measures. Prophylactic use of granulocyte colony stimulating factor should be considered to avoid dose reductions or treatment delays.
- Pharmacodynamic studies showed prexasertib treatment induced DNA damage in peripheral immune cells.

This article reports a case of advanced metastatic low‐grade sarcoma. The patient was diagnosed with an inoperable large (14 × 12 cm) lesion on his neck in September 2015 and underwent two ineffective chemotherapies in the following 4 months. Interestingly, although several pathologists could not agree on the histopathological diagnosis, the precise molecular pathological diagnosis was obtained using next‐generation sequencing (NGS) and finally brought excellent therapeutic effects. The patient was detected to have CARS‐ALK fusion by NGS and then was successfully treated with crizotinib orally. He received surgical resection of primary and metastatic lesions after tumor shrinkage. The combined treatment brought a durable response for 40 months. Although the tumor recurred in July 2019, the patient has been responding well to the second‐line ALK tyrosine kinase inhibitor alectinib to date. We performed whole genome sequencing on the patient''s primary, metastatic, and recurrent tumors and did comprehensive genomic analysis. Furthermore, our analysis results revealed that a whole genome duplication event might have happened during tumorigenesis of this case.Key Points
- To our best knowledge, this is the first report of a very successful treatment with first‐ and second‐line ALK tyrosine kinase inhibitors for CARS‐ALK fusion–positive metastatic low‐grade sarcoma.
- Molecular pathological result can guide precision treatment for sarcoma, even when the exact histopathology cannot be obtained.
- Multiple samples from this patient were analyzed using whole genome sequencing. Results provided detailed genomic characteristics and showed tumor evolution of this low‐grade sarcoma case.
- A whole genome duplication event might have happened during tumorigenesis of this low‐grade sarcoma case.

Lessons Learned
- The primary endpoint of this phase II study that evaluated the efficacy and safety of the investigational compound, AGS‐16C3F, versus axitinib in previously treated patients with metastatic renal cell carcinoma (mRCC) was not met.
- Median progression‐free survival, the primary endpoint, was 2.9 months with AGS‐16C3F and 5.7 months with axitinib (HR, 1.676; 95% CI, 1.107–2.537; p = .015), per investigator assessment
- The safety profile for each study drug was as expected, with the most commonly reported adverse events being fatigue (53%) and nausea (47%) in the AGS‐16C3F arm and fatigue (57%) and diarrhea (48%) in the axitinib arm.
- These results provide a benchmark for axitinib use in heavily pretreated patients with mRCC.

Lessons Learned
- Apatinib has potential as an effective and safe second‐line or higher treatment for patients with chemotherapy‐refractory esophageal squamous cell carcinoma (ESCC).
- Clinical safety is of potential concern when administering apatinib to patients with uncontrolled esophageal lesions or severe invasion of trachea, bronchi, or major blood vessels.
- To the best of the authors'' knowledge, this is the first prospective phase II study to investigate apatinib for patients with chemotherapy‐refractory ESCC. Apatinib could provide an alternative option for ESCC after first‐line or higher therapy in carefully selected patients.

Recently, several malignant peritoneal mesotheliomas (MPMs), occurring in young women without asbestos exposure and with fusion genes such as anaplastic lymphoma kinase (ALK) and Ewing sarcoma breakpoint region 1, have been reported. In the present case, we encountered MPM with STRN‐ALK fusion in a 17‐year‐old female adolescent. The case did not respond to chemotherapy and is currently in a clinical trial of alectinib. This is the fourth reported case of MPM with STRN‐ALK fusion. Of the 45 cancer cases with STRN‐ALK fusion in which the fusion partners were examined, all cases except for the current case showed fusion of exon 3 of STRN and exon 20 of ALK. This is the first case with fusion of exon 2 of STRN and exon 20 of ALK. Further advances in cancer genomic medicine may help clarify the clinical significance of this new fusion.Key Points
- Malignant peritoneal mesotheliomas (MPMs) can occur in young women without asbestos exposure and show fusion genes that activate anaplastic lymphoma kinase (ALK) by gene rearrangement.
- ALK rearrangement and the fusion partner can be detected by companion diagnostics and by next generation sequencing.
- Patients with MPMs with ALK rearrangement may benefit from target therapy.
