Histologic Subtypes And Immune Markers Of HER2-Amplified Cervical Cancer (ESGO 2024)
Among patients expressing 2+ or 3+ HER2 and treated with the HER2-targeting agent, those treated with T-DXd displayed prolonged progression-free survival (PFS) after treatment, with a median of 17.5 months (n=4). Conversely, two patients treated with Trastuzumab emtansine (T-DM1) experienced a poor prognosis, with a median PFS of one month...These subtypes are known to be associated with a poor prognosis with conventional therapy, making them potentially suitable targets for high-efficacy treatments. Further studies are required to confirm the efficacy in HER2-amplified cervical cancer.

HER2 and PD-L1 immunohistochemistry (IHC) expression, and HER2 genomic alterations: Associations and clinical outcomes for advanced bladder cancer. (ASCO-GU 2024)
Our study is the first to describe an inverse correlation between HER2 IHC expression and PD-L1 CPS score. Furthermore, HER2 IHC overexpression is strongly associated with HER2 amplification, but a subset of patients with high HER2 protein expression are potentially missed by genomic profiling alone. HER2 expression by IHC or HER2 genomic alteration is not a prognostic marker for MIBC pts in this cohort.

Frequency and nature of genomic alterations (GA) in ERBB2-altered urothelial bladder cancer (UBC) (ESMO 2023)
Table: 2400P Conclusions We noted important differences in co-occurrent-GA in ERBB2-altered (ECDmut, KDmut, amp) vs wt UBC, and higher mean TMB and higher APOBEC mut signature in the ERBB2-altered group. Results can help refine future clinical trial designs and help elucidate possible resistance mechanisms for ERBB2-altered UBC.

Micropapillary histology (MPUC) and extra-cellular domain ERBB2 (ERBB2 ECD+) mutations in urothelial bladder cancer (UBC) (ESMO 2023)
Background Given the early promising data with afatinib in advanced UC and the recent approval in NSCLC for anti-HER2 targeted therapy for activating kinase domain exon 20 ERBB2 insertion mutations, there is considerable interest in targeting additional locations in the ERBB2 gene in other tumor types...Conclusions ERBB2 ECD mutation-driven UBC represents a distinct subtype of UBC featuring an enrichment of MPUC histology from 1-2% to 28% incidence in ERBB2 ECD mutated UBC, and unique clinical and molecular characteristics, including differences in mutational signatures and genetic ancestry. Further exploration of anti-HER2 targeted therapy for non-amp sequence mutations in ERBB2 in UBC appears warranted.

Demographic and Genomic Characteristics of Non-Small Cell Lung Cancer Patients with ARID1A Alterations (IASLC-WCLC 2023)
This case-control study provides a mutational landscape and demographic profile for NSCLC patients with ARID1A alts. Notably our data support the finding that EGFR mutations are less prevalent in patients with ARID1A alt, which is relevant as ICI efficacy is low in patients with EGFR mutated NSCLC. The efficacy of ICI in our cases and controls is being analyzed to shed light on whether ARID1A alts warrant further evaluation as a biomarker for ICI efficacy.

Urothelial Bladder Cancer: Genomic Alterations in Fibroblast Growth Factor Receptor. (PubMed, Mol Diagn Ther)
An increased frequency of genomic alterations is observed in UBC FGFR. These have been linked to immune checkpoint inhibitor resistance. Clinical trials are needed to evaluate UBC FGFR-based biomarkers prognostic of an immune checkpoint inhibitor response. Only then can we successfully incorporate novel therapeutic strategies into the evolving landscape of UBC treatment.

RNA sequencing as a confirmatory assay and its impact on patient care in multiple cancer types. (ASCO 2023)
In order to target HER2, systemic treatment was changed to a combination containing trastuzumab and pertuzumab, resulting in pathological complete response...Staining showed high PDL-1 (CPS50), prompting a change in therapy to an anti-PDL-1 (pembrolizumab) therapy... RNA-seq is emerging as an objective tool to evaluate key diagnostic and targetable events in multiple cancer types. The use of RNA-seq can also add value as an objective measurement to confirm critical IHC findings, potentially changing clinical care.

The heterogeneous immune and molecular landscape of endometrial cancer metastases (AACR 2023)
ECM to GU (n=29, HR: 1.59, 570 days, p=0.04) had worse post-Carboplatin survival than ECP (n=3023, 1096 days) while ECM to Lung had better (n=279, HR: 0.73, 1602 days, p=<0.01). ECM to Liver (PD-1/PD-L1i: n=27, HR: 2.4, 165 days, p=<0.01; Bevacizumab: n=44, HR: 1.5, 286 days, p=0.03) had worse post-tx survival compared to ECP (PD-1/PD-L1i: n=607, 760 days; Bevacizumab: n=693, 463 days). ECM to Bone and GU organs have unique molecular alterations when compared to ECP of the uterus and have lower infiltration of immune cells. We also highlight differences in OS when comparing different ECM.

Cancer of unknown Primary (CUP): Beyond the identification of the site of origin by an integrative genomic approach (AACR 2023)
Based on CUP tumor profiling by this platform, positive treatment response has been observed in 3 out of 4 CUP patients thus far, e.g., one patient with metastatic disease that showed high TMB and immune infiltrated microenvironment treated with Ipilimumab and Nivolumab had a sustained response. Therapy in oncology is often determined by the tissue origin, making CUP a therapeutic challenge. In this study, we demonstrate the application of an integrative WES and RNAseq platform to not only predict the site of origin, but also to identify relevant biomarkers and therapeutic targets in CUP.

KRAS Targetable Mutation Profile and PD-L1 Expression in Resected Mucinous Adenocarcinoma of the Lung (USCAP 2023)
While KRAS mutations are common in mucinous adenocarcinoma of the lung, sotorasib targetable p.G12C mutation is uncommon in this distinct subtype. The association of KRAS mutations with mucinous adenocarcinoma tumor size suggests earlier somatic mutations may exist to initiate its carcinogenesis. Absent or low PD-L1 expression on mucinous adenocarcinoma cells make it challenging for systemic immunotherapy for this distinct entity.

Molecular landscape and clinical implication of CCNE1-amplified esophagogastric cancer. (ASCO-GI 2023)
"While there were no differences in OS between CCNE1-amp vs non-amp GA, CCNE1Amp was associated with worse OS after trastuzumab in the IHC HER2+ cohort (N=9 vs 28; HR (95% CI): 2.95 (1.18 – 7.34), p = 0.015)...CCNE1Amp is associated with a distinct molecular profile in EGC and resistance to HER2-targeted therapy. While CCNE1-amp tumors are thought to be generally “immune-cold,”CCNE1-amp GA demonstrated potentially improved outcomes with immunotherapy. Further investigation of CCNE1Amp as a predictive biomarker is warranted, particularly as novel therapeutics selectively targeting CCNE1Amp are under clinical investigation."

Goblet Cell Adenocarcinoma (GCA) of the Appendix: Interrogating Proteomics to Identify Potential Actionable Targets (NANETS 2022)
There were no statistically significant clinicopathologic differences between patients with HER2 2+/3+ and HER2 1+ tumors though patients with HER2 overamplified disease were more likely to recur compared to patients with HER2 unamplified disease (43% versus 0%, Chi-squared test p= .09).CONCLUSIONS For the first time we have demonstrated that HER-2 is overexpressed in a significant proportion of patients with GCAs, suggesting that this can be a potential therapeutic target to explore clinically. Furthermore, the absence of SSTR2 in GCAs suggests that the tumor is much more akin to an adenocarcinoma than low grade NET.

Genomic and Transcriptomic Landscape of HER2-Low Breast Cancer (SABCS 2022)
With some exceptions, H2L breast cancer shared genomic features with its more classically defined subset of either HR+ or HRneg disease. Notable differences in PIK3CA (an actionable mutation) and TP53 (a prognostic alteration) warrant additional assessment, as do amplifications variable between HR+H2L and HR+Her2pos groups. Our findings add tremendously to the current understanding of the molecular profile of the H2L subgroup and comparison to the classically defined breast cancer subgroups.

Clinical parameters, age, performance status (PS), comorbidities evaluated by Cumulative Illness Rating Scale (CIRS), distinguished patients in fit or unfit to conventional treatment, treated with standard doses/schedules, pembrolizumab 200 mg added to cisplatin (75 mg/mq) or carboplatin (AUC 5) plus pemetrexed (500 mg/mq) or carboplatin (AUC 5) plus paclitaxel (175 mg/mq), d1 every 3 weeks, or modulated doses/schedules, respectively. Most metastatic NSCLC patients suitable for first-line ICIs/platinum-based chemotherapy combinations were elderly, unfit for recommended doses and/or schedules. Proper treatment modulations were tolerable in unfit patients treated in clinical practice, and guarantee consistent activity and efficacy. Updated safety, activity, efficacy data will be presented.

Prevalence and prognosis of ER-loss in advanced invasive lobular carcinoma (SABCS 2022)
In this large real-word dataset, ER-loss likely occurred in 11.4% of ILC and was associated with worse OS compared to both patients with IDC and ER-loss and ILC without ER-loss. Our analysis had several limitations; notably, our definition of ER-loss was based on prior treatment, we could not distinguish between de novo or recurrent metastatic disease and time of tissue collection was not standardized during the course of treatment. Thus, additional studies are needed to confirm these findings.

Third- and Late Line Treatments of Metastatic Gastric Cancer: Still More to Be Done. (PubMed, Curr Oncol)
Overall, TAS-102, apatinib, regorafenib, nilotinib, trastuzumab, and pembrolizumab were demonstrated to be valid options in the third line scenario for mGC patient refractory to at least two lines of therapy. A multimodal approach based on chemotherapy, immunotherapy, targeted agents, a personalised nutritional programme as well as the research of new predictive biomarkers may pave the way to new strategies to identify the best treatment for each patient.

HER2 in uterine carcinosarcoma: Testing platforms and implications for targeted therapy. (ASCO 2022)
Increased HER2 positivity was detected via CISH testing compared to IHC and NGS, which may reflect the heterogeneity of HER2 amplification due to mixed histology between the sarcoma and carcinoma portion of the tumor. High concordance rates were observed between CISH and IHC. These testing platforms need to be validated by response to HER2 targeted therapies in order to develop UCS specific testing guidelines.

Acquired EGFR-resistant mutations in non–small cell lung cancer (NSCLC). (ASCO 2022)
Acquired resistance in EGFR mutant NSCLC is very heterogeneous and their frequency is still low most likely due to lack of enough sequencing of EGFR resistant tumors. While T790M and C797S mutations are well described, this report also notes a significant number of L718V mutations, primarily in osimertinib-treated pts with an original L858R. These data support the NGS evaluation of patients with resistant EGFR mutant lung cancers.

Impact of PD-L1 expression on conventional urothelial bladder carcinoma (UCB) genomic alteration (GA) profile. (ASCO 2022)
PD-L1H and PD-L1N subtypes of UCB differ in their genomic profiles. PD-L1N UCB features greater frequencies of potentially “targetable” GA, including FGFR3, ERBB2, ERBB3 and PIK3CA. PD-L1 IHC may thus not only play a role in the selection of ICPI for advanced UCB but also in designing trials that may combine ICPI with targeted therapies.

Immunogenomic characterization of biliary tract cancers: Biomarker enrichment for benefit to immune checkpoint blockade. (ASCO 2022)
Phase II monotherapy (pembrolizumab or nivolumab), and combination (atezolizumab and cobimetinib) ICB trials reported low response rates in unselected advanced BTC with a wide range of responses. A subgroup of BTC pts (iBTC) benefit from ICB. Apart from MSI-H and TMB>10, other genomically-defined subgroups such as HRD may benefit from ICB. Prospective studies are needed to evaluate a better biomarker enrichment strategy beyond PD-L1 and TMB, that can represent other immunogenic aspects of tumor neoantigen and microenvironment.
